"Southbound train arriving one minute on track one." "Southbound train on track one." "Freeze." "Stop." "Stop." "Stop running." "Stop now." "Hold your positions." "Exercise is terminated." "Hold your positions." "Hold your positions." "Exercise is terminated." "Good work." "We foiled a sarin attack." "Excellent job." "But my undercover sheriffs, they would have done better if they kept the bad guys alive." "Get information." "So we're gonna do it again." "Everybody gets set up." "We're doing it again." "Conductor." "Conductor." "Open the doors." "Open the doors." "Conductor." "Open the doors now." "Everybody, out, out, out." "So, what have we got?" "The guy in charge of the drill called it in." "He didn't want to speak to me till you got here." " James Grace, Homeland Security." " Don Eppes, FBI." "So, James, you wanna give me a little rundown here?" "We're conducting an anti-terror drill." "Testing new biochem sensors and our response." "At the end of the drill, a few of the sensors went off for real, indicating that there was some kind of a release of a toxin into the air." " Do you know what it was?" " HAZMATS identified it" " as phosgene, a relative of chlorine." " And what about all the people?" "Everybody on the train were either MTA employees or undercover cops." "I was told that six of them went to the hospital, but everybody's okay." "Wait, didn't we get a memo, right?" " That you are planning more drills?" " Yep." "This is our first one." "We got ten more in L.A. in the next seven days." " James, what the hell happened?" " We don't know yet, Peter." "Special Agent Eppes." "Special Agent Reeves, FBI." "Peter Houseman, Homeland Security." "Oversees these drills." "Glad to have the bureau's help." "What can you tell me?" "Hey, I just got here, but I can tell you you should put your other exercises on hold." " Sorry." "That's not an option." " Not an option?" "We've been planning these exercises for the past year." "I've got drills in nine different cities in the next six months." "We pack up now, we won't be coming back." "I understand but until we find out what happened, I think..." "We'll continue to run these tests." "In L.A.'s local airport, in the hospitals, in the harbours." "I'm not going to compromise the safety of Los Angeles because some janitor left the lid off a jar." "Washington thinks the chances of this being an actual terrorist attack are slim to none." "I agree." " And that's based on?" " Logic." "Terrorists go after maximum casualties." " They don't go after anti-terror drills." " That is one type of profile." "There are so many others." "You think somebody did this deliberately?" " It is your job to find them." " Oh, I'm sorry." "See, I didn't realise the FBI takes orders from Homeland Security." "Fine." "You got your work cut out for you." "And I've got a job to do of my own." " Your boss always this reasonable?" " He's right." "Stop the drills now is like turning the Titanic." "The Titanic hit an iceberg." "We all use math every day:" "to predict weather, to tell time, to handle money." "Math is more than formulas and equations." "It's logic." "It's rationality." "It's using your mind to solve the biggest mysteries we know." "Hey, Dad." "Seen Charlie?" "Right." "Forty portable chairs, banquet table and an arbour." "For Saturday." "Okay, great." "See you then." "An arbour?" "You're right, that upstairs bedroom would make a great changing room." " Good." " Val?" " Hey, Don." " Well, long time." " Since high school graduation." " Look at you." "You look great." "Thank you." "I think the last time I saw you you were driving off in that VW you had." "My clutch gave out right by Ventura." " What is going on?" " She's getting married." "Yeah, right here." " Yep." " Oh, you're kidding." " Here at the house?" " Yeah." "My fiancé and I were planning a big June wedding." "But then he got transferred to London this year." "And my mother, she flew into a total panic." "Val's parents invited us and I found out what was going on." "They sold their place and moved into a one-bedroom on Wilshire." "So I said, "It's no problem, have it here."" " Yeah, sure." "Why not, right?" " Thank you." " So you're an FBI Agent." " I had to make amends somehow." " And you, what are you up to?" " Paediatric surgery." "Yeah, she's a doctor." "Yeah, yeah." "So your dad was telling me about Charlie." "The math rock star." "Yeah, well, no surprise there, right?" "We always figured he'd do something special." "You forgot that fight with your brother when you invited Val to the prom." "What are you talking about a fight?" "He was 13." "He's gonna go out with her?" "You'll forgive me if my recollection is different." "So anyway, I hear you two work together now." "When I find him." "Not that I don't want to reminisce but that's why I'm here." "Charlie's in the garage." "No, wait." "I just saw him go out front." " All right, hey..." " Okay." " Great seeing you, Val." " You too." "You're gonna come, right?" " Sure, I wouldn't miss it." "Absolutely." " Good." " Congratulations." " Thank you." "Oh, thanks." "So this is where all those university research dollars go?" "Oh, everything you see here came out from our own pockets." "CalSci's "Minibot Chain Yank and Crank" is next Friday." "After five years of ignominy, the Physics department has ascended to finals against Engineering." "Thanks to Professor Charles Edward Eppes." "I just freestyled Faraday's Laws of Induction to triple amp the armature coil and maximise horsepower." "This thing's actually gonna pull the car?" " Six feet to glory." " Let's do it." " Okay." " You guys are something else." " This is it." " All right." " Okay, ready?" " Come on, Physics department." "Let's see." " There it is." "Check it out." " Here we go." "Oh, you see that?" " Well, it's moving the car." " Look it, come on." "All right, two feet." "Okay, half way there." "Three feet, half way." " Oh, come on, baby." " We did it." " Sorry, guys." " This is like 1998 all over again." " Hey, did you see Val?" " Yeah." "Yeah." "Doctor?" "Well, her talents always were in biology." "I take it you both knew this woman?" "We were all in the same class in high school." "Oh, yeah, I keep forgetting." "You graduated the same year." "So you're not here to talk about Val?" "Yeah, right." "Do you know anything about phosgene gas?" "A diluted form of it was released on the subway this morning." " Oh, my God." " Trying to figure if it was an accident, like, maybe a maintenance worker mixing bottles together." "Phosgene's used in the manufacture of dyes, pesticides." "It's in the chlorine family and it is highly toxic." "You know, theoretically, it could be accidentally produced by combining certain cleaning agents, but that's very unlikely." "So it probably wasn't an accident." "What was the delivery mechanism?" "Do you know if it's an air duct or a canister?" "Yeah, we don't know yet." "Why?" "When gas dissipates, it leaves a trail." "You may determine the original release point." " And if we find that out?" " You may find who released it." "Looks like we got something." "The drill participants were all MTA employees or law enforcement." "The MTA windbreaker's easy enough to get your hands on." "So it looks like the guy dumped this out here in the confusion." "And then walked away a new man." "Gas mask." "Is that a cafe latte to go?" "I love these things." "It looked like someone drilled a hole in it and then resealed it." "Well, now what?" "Now, we buy Charlie a coffee." "These coffee drinks I've seen them." "Half of my students suck down one per lecture." "Let me see it." "How's it work?" "The can has an internal heating system." "There's a button on the bottom." "You press it, and water mixes with quicklime." "It's highly exothermic, and it can produce heat as high as a 140-degrees Fahrenheit." "And it makes a really nice latte." "And quite an efficient delivery system." "Here you go." "Kept at 48 degrees, phosgene's a stable liquid." "Above that, it turns into a potentially deadly gas." "This diagram illustrates gas intensity levels throughout the subway car, as measured by first responders." "Now, using that data, I was able to run a Gaussian plume dispersion model." "A manner in which to determine the pattern of the gas release." "Now, to the naked eye, a gas release can appear as one large cloud." "A gas will spread from its release point driven by air currents, toward open doors and windows." "Obstacles in the path of the gas will affect its dispersion." "One large cloud is actually comprised of many separate plumes." "Using a generalized diffusion equation," "I was able to backtrack to find the origin point of the gas release." "Your assailant released, the gas here, precisely in the centre of the car." "Yeah, why right there?" "Well, this placement allows for the greatest dispersion." "You see, with air ducts on the perimeter, there's no way for the gas to vent out." "Theoretically it was released in a way to maximise deaths." "Remember, you said, the phosgene was diluted and it was, by mixing in a harmless additive to negate its deadliness." "Someone with this type of proficiency?" "This wasn't a mistake." "Which means this person could have taken lives, but chose not to." "Well, we know he deliberately chose to target an anti-terrorism drill." "So we're talking about a high-risk taker with a thrill-seeking disposition." "Right, it's like a game to them." "Most thrill-seekers are adrenaline junkies." "I'd say our guy is gonna strike again, only this time, he'll need to up the ante." "We're gonna get ourselves some real casualties." "Get back to the office." "Get that memo to the director." "Hey, Houseman, look, I know you're not gonna wanna hear this, but you're gonna have to put those exercises on hold." "I don't like having the same conversation twice." "Well, neither do I, but that gas was released intentionally." "By someone who's planning on doing some serious harm." "And you know this how?" "Among other things, a mathematical analysis, which I stand by." " Really?" " Yeah." "I got some math for you." "How about 52 killed in the London subway." " No." " A hundred and 91 in Madrid." " Right." " Do I really need to mention 9/11?" "I get your point, here's mine." "Because everything we know tells us whoever did this is going to do it again and next time, the gas is not gonna be harmless." "We've got chemical plants that are exposed." "We've got harbours, food supply, water, all very vulnerable to attack." "The city needs these exercises to protect itself." "I understand, but I'm telling you, if you don't stop them," "I am going on record saying you're making a mistake." "You should inform your people that are partaking in these exercises." "And totally corrupt the exercises?" "That would accomplish nothing." "Look, I've had some experiences making tough decisions like these." "When I oversaw base security as a consultant in Iraq." "The question is, would you rather write two letters of condolence or 200,000?" "Hi there, gentlemen." "What happened, Larry?" "Charlie here, draft you into another one of those investigations?" "You're not gonna believe this." "Somebody attacked an anti-terrorism drill on the subway." "Was anyone hurt?" "No, fortunately, our budding terrorist utilized a diluted form of phosgene gas." "Hey, Charlie, I can use a hand getting the yard ready for the wedding." "Yeah, Don needs to figure out what happened ASAP." "Come on, she was your friend too." "Oh, I guess this is what I get for volunteering?" "Yeah, for volunteering my house." "Yeah, that's fair." "I'm providing house, you provide labour." "I understand that Don and Charles went to school with this girl." "Oh, yeah, your friend, Charlie, had quite a crush on that girl." "Yeah, I was 13, and she was my lab partner." "You weren't casual." "Especially when Don took her to the prom, remember?" "They had a wrestling match about it on the lawn." "Isn't it nice having a living history of embarrassing moments from my childhood?" "Oh, no, no." "I'm quite enjoying the vision of a young Charles Eppes moved to violence by a girl." "Oh, he was moved, all right." "You know what, can we?" "Why are we talking about?" "This was something that happened..." "I have work to do." "We have..." "We have to get work done." "Yeah." "Well, I guess I have to clip the hedges, myself." "How'd it go with Homeland Security?" "It didn't." "The drills are going forward." "They have three tomorrow, and four the day after that." "Well, maybe keeping the exercises in play is good." "It's limiting the number of targets." "What?" "There's 10 altogether, we don't have troops to cover all them." "Maybe you don't need to." "Charlie can help us out there." " Oh, yeah, what do we got?" " Gentlemen." "Subway security camera caught our guy on tape." "Witness saw him dumping his gear in the trash bin." "We ID'd him as a Roger Holstein, 31, ex-Army Special Forces." "Body art was the tip-off." "That tattoo right there?" "That means, he's a CT team operative." " CT team?" " Counter Terror." "They're soldiers trained to role-play our enemies, then mimic their tactics." "Including terrorist's simulations." "They test the security at military bases and weapons stations by staging mock attacks." " And the subway strike?" " It's right out of their playbook." "This guy Holstein?" "He's been doing the exact same kind of work as a civilian contractor since he was discharged from the Army." "Their last job was two months ago." "His team staged a mock attack on Mirabo Labs, a private chemical facility." " That's where he got the phosgene?" " Yeah." "And you say these guys usually work together in teams?" "Always." "Can you playback the tape?" " Yeah." " And stop it right there." "Can you zoom in on his ear?" "Highlight that." "Right there." "He's wearing an earpiece." "Holstein wasn't giving orders, he was taking them." "And was this guy in charge of the operation at the chemical plant?" "No." "It was another ex-Army, ex-CT team guy." " You've got his jacket?" " Yeah." "Glen Nash, former Special Forces." "Served in Iraq, had a medal of valour." "Retired from Army service in '03, went into private contracting, mostly overseas except for a few jobs in the States at places like Mirabo." "His jacket says he has training in psy-ops, cyber-warfare and covert operations." " What?" " In 2002, when he was still in the Army, he led a CT operation." "They penetrated security at a naval base and stole a submarine." "A submarine?" "And he only had seven men on his team." "Look, I want his full background." "I want team photos, everything." "I wanna know where he is." "I mean, you tell me, they can steal a submarine from a naval base with seven guys?" "Think how easy it would be to attack a wide, open city." "When did you last see your brother, Miss Nash?" "Couple months ago." "He was in L.A., doing some security work." "So I let him crash on my sofa." "One morning he was gone." "No goodbyes." "Classic Glen." "Any idea where he went?" "We're not that close these days." "Why is that?" "Glen's changed." "You know, he served in Iraq." "Yeah, we looked at his service record." "Glen lost men over there." "It hit him pretty hard." "It'll do that." "You were there?" " Afghanistan." " Then you know." "Is my brother in some kind of trouble?" "Miss Nash, right now, we just need to talk to him." "But sooner rather than later." "I wish I could help you." "Megan says the way we're gonna stop these guys is to catch them in the act." "You know what?" "She might be right." "Well, Charlie, look, I wanna stop something terrible from happening." "You know, I don't wanna clean up after it." "I understand." "I'll apply Site Percolation Theory." "Site Percolation Theory examines how a suspect navigates through a maze of lattice points, obstacles in order to achieve an objective." "Come here." "Think of the exercise like a pachinko game." "Our attacker is the ball descending through the maze." "And the nails are like physical obstacles, alarm systems, locked doors." "The holes are security traps laid in his path." "Now, our guy has to navigate around the obstacles and avoid security in order to reach his objective." "A different pachinko game will yield different lattice points." "That just like different exercises will present different security measures." "Absolutely, now, by analyzing the choices, our attacker made to led him to infiltrate the subway," "I may be able to postulate an m.o." "However, I'm gonna need data from the remaining exercises." "Well, I'll talk to Homeland Security." "Sure." "Great." "Hey, did you hear what Dad's doing?" "Oh, my..." "He's too obsessed with this wedding." "Seriously, he went out and bought himself a copy of Bride's Magazine." "Our little wedding planner." "He says because he has two sons, this may be the only chance he'll have to get to throw a wedding." "Kind of weird Val getting married at our house, though?" "Don't you think?" "Even weirder because I liked her and, you know, you took her to the prom." "Oh, come on, you're still upset about that?" "No, I..." "Remembering that brings back other stuff." "Like what?" "Like what it was like to be Don Eppes' 13-year old, brainiac brother." "Oh, come on, Charlie, don't start." "It wasn't that big a deal." "Not for you, but high school sucked for me, Don." "Man, I was a little kid." "Everyone was years older than me." "And yeah, there was this one girl who didn't treat me like I was different." "She was nice to me." "It was no easy trick being your brother, either." "You're five years younger than me, we're in the same grade." "I'm like an idiot next to you." "I'm sorry if I was better than you at something." "Whatever, man." "You're the one that asked." "So predicting how Nash will strike is only half the battle, it's not gonna tell you where." " Well, can you tell us that?" " No, but Nash will." "I'll tell you what." "Let me start by looking at his military operations, then I think I'll be able to tell you more." " Okay." " Okay." "We pulled jackets on the rest of Nash's team from the Mirabo Labs job." "Now, Holstein we know about." "The others are, Jason Small, demolition specialist." "And Henry Olerud, an electronics geek." "All right, let's say that Nash has put together their reunion tour." "And he's targeting the exercises." "It doesn't tell me why he is going after Homeland Security." "This might." "Nash has been working as a contractor in Iraq this last year." "And the base he was working out of was supposed to be secure, but it wasn't." "In April, they're hit by suicide bombers." "He lost two men in his team." "How's that connected to Homeland Security, though?" "Because the same lapses in security that he saw there, he sees here now." "My guess is he's decided to call attention to it." "How?" "By gassing the subway?" "In his mind, he's found a way to exert control over a situation he was helpless in." "Emotions aren't rational, Granger." "Revenge is just an emotion." "I checked their background." "Nash's CT team fell off the grid after Mirabo." "Cell phones, bank statements, credit cards, it all stopped dead." "But wait, he had a sister, right?" "She said she doesn't know where he is." "Let's get her on surveillance." "I mean, if we don't find him, he's going to find us, you know." " Hey." " Hey." "Master plans for all the remaining exercises." "Oh, thank you very much for your cooperation." "I appreciate it." "I think you should take a look at this first." "Our department keeps records of all threats made against Homeland Security personnel or operations." "Nash, he sent letters, making a lot of noise about how easy it would be to trash Houseman's anti-terror drills." "I'd appreciate it if you don't tell Houseman I gave you that." "Yeah, absolutely." "But why didn't he give it to us?" "Well, he doesn't like to respond to what he calls idle threats." "I'm glad you don't agree." "You know, I did my time in the Army, the first Gulf War." "I've met men like Nash, Special Forces." "In my experience, they don't bark unless they intend to bite." "New algorithmic mapping system?" "It's a seating map for the wedding." "My Dad finally found me a job I can help him with that's interesting mathematically." "Yeah, well, it seems just a little elaborate." "Well, it is a complicated series of evaluations:" "Dynamic traffic flow, graph analysis, acoustic patterning." "Okay, I tell you, none of this explains why I always get stuck sitting between the great aunts and the cigar-smoking cousins." "Well, diversions aside, this case I'm working on is presenting some difficulties." "Anything you hope to discern?" "A pattern in Glen Nash's past acts, a key to his target selection." "Yeah." "Anything else going on with you?" "Just the other day, you know, when your father recalled the amusing anecdote of you and Don fighting over the girl." "Yeah." "What about it?" "It's just, you know, you didn't seem all that amused." "There's some stuff between Don and me that's not worked out." "Have you talked to him about that yet?" "No, it was high school." "Well, you know, sometimes, the path to closure is as elusive as the path from row three to row six." "It's certainly not as simple as it appears." "People always desire to have the best seat, which is the row directly behind the families, but no matter how you map it out, there's always gonna be some seats, some targets harder to get to than others." "That's the commonality." "Out of 30 CT team operations, all were against military bases, and high-security labs, but I know that in the military," "CT teams often choose their own assignments." "It seems like Glen Nash made a point of choosing the most unassailable targets." "Well, there's your pattern." "Megan, we ran an employment check on Nash's former team." "Prior to Mirabo Labs," "Holstein, Small and Olerud all worked jobs in construction, home building supply and electronics wholesale." "That doesn't track." "Cowboys like this don't take $10-an-hour Mcjobs." "These Special Forces guys are trained to live off the land and make use of what's readily available." "Like turning a convenience store item like a cafe latte can into a chemical bomb." "Yeah, we figured maybe these guys helped themselves to phosgene gas while they're working at the labs." "They chose other work sites for whatever they needed to steal." "We should talk to their former employers," " to see what else went missing." " Where's Don?" "He's with the Homeland Security guys in the room." "Great." "Because I think I may have an answer for them." "After the first World Trade Center attack in 1993, mathematicians at the NSA tried to predict other attacks by evaluating likely target choices using a linear discriminant analysis." "Agent Eppes, am I here for a math lecture or a substantive discussion of the problem at hand?" "Well, how about both, Mr. Houseman?" "Based on past acts, I've deduced that Glen Nash doesn't just prefer hard targets." " He goes for the hardest." " The greatest security challenges." "Given this fact, I've applied my linear discriminant analysis to the 10 remaining exercises." "And I've calculated threat assessments based on a series of variables:" "Number of ingresses, egresses, number of security cameras, police presence, proximity to the freeway, and so on." "Now, from these variables, I've rated the targets from softest to hardest." "And I believe that Nash's next target is city hall." "We have an exercise there tomorrow at 9 a.m." "So that gives us, what, 11 hours?" "That's enough time to run Nash's m.o." "through site percolation theory algorithm, and that may tell us how he'll attack." "We have a breach at the Homeland Security office." " What?" " What?" "It doesn't make any sense." "The Homeland Security office isn't a hard target." "And to strike two days before the scheduled exercise breaks Nash's m.o." "He's telling us we're on his schedule now." " Nothing was missing." " Security says no." "Is it possible they tried to download plans for the exercises, and triggered the alarm that way?" "Tech guys say the firewall hasn't been breached." "I want every inch of this building searched again." " No one has entered, Peter." " Every inch, James." "And your guys didn't get anything off of these video cameras?" " Or the motion detectors." " So nobody actually made entry." "But they want us to believe they did." "Why would Nash want to trigger an alarm if his team never entered?" "It's not a game if there's no objective." "Right." "So tripping the alarm will accomplish what?" " Well, it brought us all here." " Nash is trained in cyber warfare." " He hacked into their system, right?" " But why?" "What's the point?" "What if we're the point?" "If he can hack into their security system, why not into their video surveillance?" "They're both on the same circuit." "So he's watching us through those cameras." "Okay, he's watching us do what?" "He's watching us respond." "It's counter surveillance." "If the guy goes through the trouble, why not steal Houseman's security plans for the rest of the exercises?" "Because then Houseman might cancel them." "Our boy Nash wants to make sure those exercises stay in play." " As a target." " Okay, thank you." "I just checked on those other jobs that Nash's guys had." "You're exactly right." "There's a bunch of stuff missing:" "blasting caps from a construction site, a pesticide called Cordex missing from the home supply store, a bunch of cell phones from the electronic shop." "Palestinian suicide terrorists, they use Cordex to mix with explosives." " Plus blasting caps and cell phones." " Nash is making a bomb." "We're talking about concrete evidence that Nash and his men have an explosive device." "And my psych workups indicate that he's getting tired of sending you messages you don't listen to." "If we stop the exercises, we give what he wants." "And you don't, you are literally daring him to cause real casualties." "I think we should listen to what they say, Peter." "All right." "We postpone the exercises until you get Nash." "Tell our people to stand down." "Well, it went a lot easier than I thought it would." "You don't think a bomb going off is enough of a motivator?" "What part of his personality says he can take a suggestion?" "Okay." "Well, what's changed since the last time we saw him?" "The break-in at Homeland Security." "He seemed pretty rattled." "Which we assumed was because Nash hit him where he lived." "You think something else scared him?" "Maybe." " Hey." " Hey, brother." " What's up?" " Dad's lasagna." "It's actually worth digesting." " Why don't you grab a plate?" " I'm good, thanks." " You sure?" " Yeah." "What do you got there?" " High school year book?" "No way." " Yeah." "I don't remember you being next to Val." "Oh, yeah." "Val Eng." "Charlie Eppes." "I thought it was part of a greater plan." "What, I ruined that?" "What's your quote here?" "Eternal nothingness is okay if you dress for it." " Woody Allen, that's good." " Yeah." "I don't remember you being all that funny." "Oh, and yeah, and you were hilarious, right?" "Man, I totally didn't get you." "We totally didn't get each other, did we?" "No, negative." "We could have never done this work together as kids." " No way." "Can you imagine that?" " Can you imagine that?" "I mean, we're doing all right now, right?" "Somehow, yeah, we're doing all right." "Charlie, look, you know, if I did stuff that hurt you when we were kids I'm sorry." "Thank you." "You don't have to." "I was 13." "Yeah, exactly, you were 13." " She was..." "She was so hot." " She's still hot." "Just think how happy Dad would be if one of us married a doctor." "I think he'd be happy if I married someone with a pulse." "At this point, yeah." "Hey, listen." "So something Larry said got me thinking about the targets." "It doesn't matter because they cancelled the exercises." "But we're gonna have to catch Nash the hard way." "That's just it." "I'm not so sure the exercises were the target." " What do you mean?" " Come on, bro, I'll show you." "So I based my linear discriminant analysis on Nash's past operations, which yielded a preference for a hard targets." "Missile silos or battle command labs." "Right, which is why you thought he'd strike city hall." "But in focusing on Nash's patterns of behaviour, I overlooked something." "The subway, the office of Homeland Security," " those are soft targets." " Which don't fit his m.o." "So we've either been looking at the wrong guy..." "Or the wrong targets." " Good day." " Hey." " Good morning." " Good morning." "Tape from the Homeland Security Office?" "Yeah, I'm trying to see what Nash was seeing." " He's watching us." " Right." "That's us, but watch Houseman." "He's checking out his laptop." "Look at his face." "Yeah, okay." "I see the eyes, the jaw, the tension." "Something on that screen scared him." "What if Nash wasn't just hacking into their security system?" "What if he was hacking into Houseman's computer?" "So he wasn't watching us, he's watching Houseman." "Whatever message he sent was received loud and clear." "Well, back up." " A little more resolution." " Yeah." ""K.I.A."" "Killed In Action." "He's talking about American troops killed in Iraq." "Call Homeland Security." "Get a bomb squad." "Tell Houseman he's going into protective custody, and that's willingly or unwillingly." "See, Charlie thought the exercises weren't Nash's prime target." "So he's going after Houseman, not the drills." "Houseman didn't show up for work." "They've been trying to find him all day." "Surveillance just saw Nash go into his sister's house." "Let's get over there." "There's our guy." "All right." "We go on my command." "Just hold." " Nash's sister." " All right, you two deal with her." "Let's go, let's go, let's go." "Miss Nash." "Miss Nash." " Come with me." " Oh, my God." " FBI." "FBI." " FBI." "Who called 911?" "Get your hands up." "Get them up." "All right, just stay cool, partner." "Everything's gonna be all right." "One more step and I'm gonna put a hole right through you." "Step away from the door." "Step away from the door." "Get down on your knees." "Down on your knees." "Hands on your head." "Check it out." "Get them on your head." "Most people use a pot rack to hang pots." " Where's Houseman?" " Who?" "Where's the bomb?" "You're sure asking a lot questions for someone who's trying to make me think you got all the answers." "Look, you don't wanna mess with me." "It's over." "I'm your only hope." "It's never over, agent." "Not until the last man's standing." "I hate to pee in your cornflakes, but I don't know where Houseman is." "I got nothing to do with this." "You had nothing to do with the threats against the exercises?" "Freedom of speech." "I spent my adult life defending the Constitution." "I figured I'm entitled to use an amendment or two." "Don't clip this on the Constitution." "This is about your men dying in Iraq." "We pulled background checks on the Homeland Security personnel." "We know that Houseman did a consulting gig in Iraq before he worked for the department." "It was his team who drew up the security plans for the air base where your team members were killed." "He made a lot of money doing it too." "You sent a letter to the Pentagon." "They didn't listen." "Well, I bet that pissed you off, huh?" "So you found another way to be heard." "Did you ask your team to steal phosgene gas from Mirabo Labs?" "The same gas that was used in the subway?" "Hey, if that happened, it wasn't under my order." "All of a sudden you weren't in charge." "Why do I have a hard time believing that?" "After the Mirabo job, we all went our separate ways." "I wanna know where they are, where the bomb is." "I wanna know where Houseman is." "And that's your only shot at a deal, you hear me?" "If I were in charge of this operation, we wouldn't be having this discussion." "Because there's no way in hell a bunch of feds would've caught me, pants down, at my sister's house." "I'm not that stupid." "We just talked to Nash's sister." "He hasn't even been in the country for the last four weeks." " Where was he?" " He's been in Mexico in drug rehab." "After what happened in Iraq he started using." "The rehab clinic confirmed Nash has been there this entire month." "Yeah, Iraq messed him up." "Just not the way we thought." "All right, so if not him, then who?" "And why are they after Houseman?" "This Army file may have the answer." "I just got to thinking, who served Nash up to us as a suspect on a silver platter?" " Houseman's number two." " Eppes." "Nash isn't the only ex-Army guy who lost men." "Different Iraq war, same story." " On our way." "Houseman was spotted." " Where?" "Homeland Security with James Grace." "You sure Security's right?" "There's no good reason for Grace to be on the roof." "Okay, guys, I got him." "Grace, get your hands up." " I don't think so." " Get them up where I can see them." "I wouldn't get any closer if I were you." "I got him on speed dial." "All right, we'll need a bomb squad." "Set up a perimeter." "Aren't we in it?" "I need a perimeter around the building." "There's a bomb on the roof." "We pulled your file, Major Grace." "You're Special Forces yourself, like Nash." " Him and his team served under you." " All those men were great men." "Is that how you'll make your point?" "Blowing up a bunch of FBI Agents?" "There's only one person here that deserves a body bag." "Him." "James, what the hell did I ever do to you?" "Me?" "Nothing." "But those men in Iraq, you let them think they were secure." "And you're doing the same thing now." "Here." "I was trying to protect lives, the same as you." "How?" "By staging these drills?" "Everything's preplanned, guaranteed for success?" "You want a real exercise, Peter?" "One with real risk?" "You got one, right now." "That's what this is, isn't, major?" "An exercise." "I want him to feel what those men felt in Iraq." " For real." " You've accomplished your mission." "Let him go." "That bomb's not real, is it?" "You think I would dishonour the men that fight for this country?" "By killing a defenceless man like him?" " All right, relax." "Come to me." " What?" "Yeah, feel it, Peter." "Feel it." "Like I said," " it was just an exercise." " Yeah." "Yeah, I hope it was worth it." "If it gets the message through to people like him, absolutely." "Can I just adjust your tie?" " Acting like I'm getting married." " Boys, boys." " How do you like the flowers, huh?" " Looks great." "I was thinking of getting potted kumquats but..." "Dad, whatever you did, the place looks beautiful." " Absolutely, good job." " You throw a great wedding." " Remember that, both of you." " Here we go." "Mr. Eppes?" "I just wanted to thank you." "No, it's Alan." "And you look absolutely lovely." "Thank you." " That's a beautiful bride." " So, where's the groom?" "Oh, Ben's over there." "I better get back inside before he sees me." "Catch you after?" " Okay." "Congratulations." " Thank you." "And he's a doctor too." "So am I, Dad." "That's what I meant." " Are you Charlie Eppes?" " Sure." "Why not?" "I'm Bree." "Bree Eng." "Bree Eng?" " You're Val's cousin." " Right." "Wow, you were so little." "I'm not so little anymore." "I was looking for an escort." "Sorry." "Groom's side." "Lead on." "Okay." "Your cousin looks beautiful." "Thanks." "I know." "I was there." "This way." " Thanks." " Nice to meet you." "It was very nice to meet you." "He better close, though." "Kid's gotta learn how to close." "Yeah, that's what he needs." "A seminar from the dateless wonder." "I don't see you with a date, pal." "Who says I don't have a date?" " The caterer?" "Nice." " Yes, the caterer." " She has a daughter." "Very cute." " That's all right," " I can take care of myself." " Take a look." "There she is." " That's her daughter?" " Yes." "See, that's food for thought." "She's cute."
