"Code 9." "A nuclear attack on London." "In bomb terms, the blast was relatively small." "But the death toll wasn't." "Over 100,000 incinerated, and many more given a death sentence by radiation." "For some people outside of the blast zone, life continued almost as normal, but after the attack... nothing in our country would ever be the same again." "British authorities have commenced Operation Sassoon, the mass evacuation of London and surrounding areas." "Relocation Centres have been set up by the government in the North of England, for all those made homeless after the attack." "From its temporary base in Manchester, the government have introduced controversial new security measures," "as well as ordering a complete re-structure of security services." "Why would MI5 be interested in recruiting somebody with your criminal record?" "Your straight guys didn't exactly save the world, did they?" "I've seen the reports, terrorists are getting younger, so you're probably looking for younger spies." "Am I right?" "I was going to be a doctor." "Then I realised I didn't want to be a doctor any more." "And what?" "You want to be some kind of action hero?" "Well, now you mention it...!" "Protect my country." "That's got to be what you want to hear, right?" "Funnily enough, it actually happens to be the truth." "I was far enough away from the blast not to get burned." "But the radiation made me sick." "I just want to help while I still have time." "I know the security services have to change, I want to be part of that." "Make sure no-one does this to our country again." "Contact established." "Alpha Team status report, please?" "She's on top of things." "Both our units are on the ground." "Alpha Team have made contact." "No news yet from Delta Team." "Ten days to the PM's visit, Rachel." "I have to assure the Prime Minister's team this region is safe." "Ow!" "Jesus!" "Sorry." "I get a bit carried away." "Haven't seen you here before." "You've not been looking hard enough." "Obviously not." "Gonna go powder my nose." "Don't you go anywhere." "Keep an eye on her." "Vik, give me some news." "Running a bit low on courgettes." "Very funny." "I must have missed the scene where Jason Bourne was stacking shelves." "Here's our man." "Target on the move." "Tip off about the warehouse is coming good." "Delta Team spotted a major player." "Good." "Don't men know how to floss?" "Looked like your tongue was doing it for him." "Gotta make it seem real." "Tongue?" "OK, Got it." "Looks like you tore him a bald patch." "SHE GASPS" "Rachel, we're out." "Well done, get the samples in for analysis ASAP." "We should have a positive ID tonight." "Excellent." "What's happening with Delta Team?" "Status report due in one minute." "Why are you taking pictures of me?" "Stock..." "We're just monitoring stock." "Gatecrashers." "Two." "Get here now." "Delta Team report, please." "You been eyeing me up for a day or two." "You want my business, you gonna have to do better." "Peppers?" "There supposed to be here." "They're not here." "On you go!" "Oh, OK." "Right, sorry." "OK, just looking for..." "On you go!" "On you go!" "Vik, Jez, report please?" "Delta Team - report?" "I'm not getting any response." "No use looking at me." "Tonight, you're in charge." "Calm authority." "Remember, Rachel, the person controlling the op has to stay focused." "Urgent status report required now." "Vik, Jez come in, please?" "Oh God!" "Have you killed him?" "Let's hope so." "Don't just stand there!" "He called for back up." "Let's go!" "Urgent status report required now." "Vik, Jez, come in, please?" "What the fuck?" "!" "Oh, my God!" "Oh, my God!" "Oh, my God!" "Seems the infantry's already arrived." "There's more?" "That was close!" "Who the hell are you?" "Charlie Green." "He's the final member of Field Office 19." "I still can't work out why you called." "How can a mathematician like me help save the country?" "You never even said where you heard about me." "I've had Charlie tailing Delta Team for the last few hours." "Which was kinda fortunate for them, really." "The ops tonight show that our fears for the PM's safety are justified." "And it looks like there's an attack team coming together." "Now, you did well tonight, but you need to keep doing well." "So don't enjoy yourselves too much welcoming your new colleague." "Let's reconvene at 0700 hours." "Sleep well." "Night." "OK, let's start the initiation games." "Yeah!" "Got the blowtorch?" "I thought sexual humiliation came first." "Or we could go back for beers and you can tell us how you got here." "Sounds a much better idea." "Although I'm not much of a drinker." "What do you bring to the party?" "Well, I can prove Fermat's Last Theorem." "I'll get the party hats." "Really, look..." "Charlie, this is the Union Jack Challenge." "You have to do it, all right?" "It's not that I can't do it, it's just I don't want to..." "Come on!" "Get some Britannia inside you!" "Come on!" "Come on!" "One!" "THEY CHEER" "Two!" "Three!" "That's easy." "There's my girl!" "How are you, Hannah?" "Dear me, bit of a comedown from Thames House." "Oh, look!" "They've made a little diagram!" "And here we have a revolutionary new structure of field offices, staffed by new recruits, with only one year's experience." "It's never gonna work though, is it?" "We know what we have to do - be out there among the communities, target the young." "We're already making it work." "Oh, of course, loyal." "Come on, though." "25% of officers wiped out in the bomb." "Half the remainder migrating to the private sector." "MI5's been gutted." "What do you want, Neil?" "I've come to offer you a job." "Is that really why you're here?" "Come on, Hannah, you're wasting your time here, and your talent." "Training kids to do the work of grown-ups." "By the time they're any good, MI5 will be extinct." "You have no idea how good they are..." "Anyway, time was, you defended the old ways." "Until I realised how good the opportunities were outside." "That's why I got out." "You got to that point yet?" "I'll triple what you earn." "Name your price." "Come on, Hannah." "You can't stay here." "Come over to the slightly darker but much more fun side." "Your three minutes is up." "Never say I didn't try and throw you a lifeline." "Oh, God." "What am I doing?" "Won't be the last time you ask yourself that." "What were you doing before your training?" "Uni." "You came straight from college?" "Well, I had two weeks in Tenerife in between." "Not much experience working in a team, then." "Chess Club doesn't count, right?" "How about you?" "Previous career, I mean." "Police constable." "I was in my third year when the bomb happened." "MI5 were recruiting." "Thought it was my chance to do something more than catch burglars." "Although, I was pretty good at catching burglars." "Even if you do say so yourself." "And what are you good at?" "OK, without wishing to come across as a nerd..." "I think that's exactly how you wish to come across." "It's a useful defence mechanism." "Applied statistics." "Real-world use of probability to forecast outcomes." "OK, you are a nerd." "And how are you useful to us?" "I analyse risk, forecast scenarios, outcomes, level of danger." "Life..." "Life is just one long probability question." "You know?" "You're in the blast zone." "You're not in the blast zone." "Life turns on a sixpence." "Is another way of looking at it." "Seems we've got a good team here." "Esprit de corps and all that." "Strange." "If it weren't for the bomb I might never have known any of them." "Jez, maybe..." "But I'd have been smacking a confession out of him in a cell." "What about Hannah?" "Hannah's the best person you could ever work for." "I'm glad you're joining us, Charlie." "Oh, thank you." "You're nice." "I didn't know if anybody would be nice." "I thought you'd all be...tough spies." "Talking like...spy code or something." "We're friendly enough." "Hey." "Sorry to interrupt." "You haven't." "We were just chatting." "Come join us." "No, it's cool, I'm heading back in." "Kylie says it's another drink for every minute you're out here, so..." "There we go." "No, that's my limit." "Wuss." "So, you all live here together, then?" "Except Jez." "Thinks he's too good for us." "Actually, where is he?" "Done his disappearing act again." "Doesn't even say goodbye." "He does that a lot." "We reckon maybe he fights crime by night, using a secret identity." "Mrs Linda Cook?" "Mr Steven Cook." "Sarah Cook." "Weren't you here last week?" "I'm here every week." "All ID cards on display with the picture clearly visible!" "All ID cards on display with the picture clearly visible!" "Uh, I've lost my wallet." "Must be down your sofa." "Hand, now." "Last name Green." "Charlie Green." "Sorry about that, sir." "He called me "sir"." "How cool is that?" "That's nothing." "Someone called me a "bloody Paki" yesterday." "How cool is that?" "How exactly is that cool?" "Old school insults are making a comeback, which I find reassuring." "You should explain to your mum that you find that term completely unacceptable." "Why do they do it?" "Because they're politicians." "What's up now?" "Wait till you hear what Central Command have sprung on us." "How's the head?" "Yeah, good, fine, raring to go." "How about you?" "On the pain killers already?" "No." "I'm fine." "The Prime Minister's visit has been brought forward by ten days, that gives us exactly..." "Six hours." "Six hours to prepare." "OK." "Update me on the DNA tests from the club." "Have we ID'd Kylie's squeeze?" "Yeah, but it's not good news." "Theo Danakis." "Shit..." "Come on!" "Do what ever it takes to get that info." "Who is he?" "Arms dealer." "Specialises in supply and disposal of arms for big hits." "The broker and the hoodie kid from the warehouse?" "Hospitals still given us nothing." "Flynn Dixon got quite a whack, though, he's gotta be getting some treatment for it." "I've spoke my assets." "There's crackle about Jermain Lee arriving in town." "Jermain Lee is one of the highest-paid mercenaries in the country." "So, we know of three of those involved in this conspiracy." "Kylie's little friend from the club is Theo Danakis, the arms dealer." "Flynn Dixon hiding out among the fruit and veg is the broker organising the hit." "But there is no hit without an assassin, we must get a visual on Jermain Lee." "The PM's definitely the target?" "It's rumours of a hit on the PM that's put us on to our targets in the first place." "Jez - go and work your assets." "What should I do?" "Come on, you can be my lucky charm." "Thought you were inside." "Does it look like it?" "Who's that?" "Don't worry about him." "And don't look at him." "He likes to fuck people up if they look at him." "Serious?" "Jermain Lee..." "The hitman." "I told you, I know nothing about the geezer." "You're lying..." "He can shoot the head off a matchstick from a mile away." "We know that, obviously." "What else have you heard?" "He's Mr Particular." "Especially about food." "Any other useful stuff?" "Favourite colour, maybe?" "He's like, proper obsessed." "Only eats burgers like, and only a certain type." "Organic meat, cooked for X amount of minutes, no sesame seeds on the bun, see what I'm saying?" "So how much is that worth, then?" "We'll let you off with a slap." "We had such a connection last night." "I think we need more time together." "So, in brief - who did you last supply a weapon to?" "What?" "OK." "Look normally, this would be fun." "But today, we're in a rush." "I'm gonna ask you again." "And if you don't tell me, my friend is gonna shoot you in the big toe." "Was it Jermain Lee?" "Who?" "You fuck!" "You shot me!" "You fucking shot me!" "In the big toe." "Yep." "I did." "Sorry." "It's my fault, I mustn't have been clear enough." "You can't do this!" "Can't we?" "Didn't anybody tell you?" "New world, new rules." "Next he'll shoot you in the bollocks." "No." "Really?" "You wouldn't." "He's my bitch." "He does what he's told." "You're bluffing!" "You thought I wouldn't shoot you in the toe." "Look what happened there." "So I'd take that into account when assessing your next move." "It's a very simple question." "Did you supply a great big gun to an assassin called Jermain Lee recently?" "Five seconds." "Four." "Three." "Two..." "Danakis just got talkative." "He provided Jermain Lee with an AK47 Takedown Sniper Rifle." "Organic meat." "Cheese on the relish." "No sesame seeds on the bun?" "I hate to sound impatient but could we guarantee the PM's safety before thinking about lunch?" "Jermain's anal about his food." "Mr Particular, my asset called him." "And do you deliver yourselves?" "Right." "Right." "Great." "I'll tell the DFO we're following a cast-iron lead." "One second." "I've got a take-away company that has delivered a burger of exactly this description for the last couple of nights." "To a kid." "No more than 15." "The hoodie!" "From the food warehouse?" "The hoodie is Jermain Lee." "One of Britain's most feared assassins is a 15-year-old kid with a burger fetish?" "Let's find him." "I'll talk to the DFO." "Let's go." "Hmm, DFO?" "Sarah Yates, Director of Field Operations." "Hannah's boss." "OK." "Does my expression say to you I'm about to pick up the phone and cancel the PM's visit?" "Just because one of my Field Offices isn't up to the job of protecting him from a teenager?" "The age of the finger that pulls the trigger makes little difference to the impact of a high-velocity bullet." "24 hour delay, that's all we need." "In 24 hours he will be in Edinburgh." "They seem quite confident they can protect him." "If you'd stuck to the original schedule, we'd have them by now." "If you don't think I'll ask them to cancel - a correct assumption, aren't we rather wasting time here?" "I want it recorded that I urged you to postpone the visit." "Do you know how many threats to the PM we receive?" "Yes, but I believe this is different." "Everyone believes their fears are different." "Don't try and convince me to cancel the visit." "PHONE RINGS That's not going to happen." "Take it." "It's bound to be more important than this redundant conversation." "You're making a mistake, Sarah." "It's on the record, Hannah." "Now do your job." "Yes?" "It's Rachel." "We've got a location on Jermain Lee." "Hotel room, paid in cash, food delivery matching his tastes..." "Vik's cross-referenced the hotel CCTV with a picture from the compound." "Which hotel?" "The Laurant." "On the square." "Which square?" "This square." "It's part of the convoy route." "Lee's in the room now." "He's casing the shot." "Dry run." "I'm on my way back." "You need to secure the hotel premises." "Discreetly." "Jermain Lee is not to know we're onto him." "We can't afford to lose him." "PHONE RINGS" "Hello?" "'Hannah, we need to talk." "You have to listen to me.'" "I'm done listening to you, Neil." "'It's really in your interest to meet me again." "Don't just...'" "Stopped listening to you a long time ago." "The fire escape stairs at rear, my colleague'll take you down the external stairs." "In position in 306." "In position." "Third floor secure." "There's movement in the window of 307." "He's opening the window." "Something's wrong." "What're you talking about, Charlie?" "He's in position too early." "He's casing the shot." "Stay focused." "It's not right, why open the window, if he's only casing?" "We're in the middle of a grab." "I don't want any dissent." "Yep?" "It's Charlie." "Charlie Green." "I know who you are." "Something isn't right." "What d'you mean?" "I'm at check point." "Where are you?" "I can see you..." "Hannah!" "Charlie!" "Status report!" "She's been shot!" "Let me through!" "Let me through!" "Charlie..." "I've called an ambulance." "Stand back, please!" "Rob, get out to her!" "Jez, Kylie, go!" "Make sure you take him alive!" "Charlie!" "It's OK, it's gonna be OK." "Charlie..." "Excuse me, please." "I'm a doctor, let me though." "It's all right, she's OK." "Gimme your hand!" "Jermain. listen to me!" "Give me your hand!" "I can't...!" "Hold on." "Jermain we can work it out." "We can work it out." "Give me your hand." "Hold on." "Hold on." "Shit!" "It's all right." "She's OK..." "Rob?" "No, no, no, she can't be!" "Hannah...!" "Hannah..." "PHONE RINGS" "OK." "Yates is waiting for us inside." "The assassin fell off the roof while you were in pursuit?" "Yes." "We tried to save him." "Who hired the assassin?" "We don't yet have that information yet." "We'd assumed that the hit was focused on the Prime Minister." "We recovered Hannah's photo and details of the square from Jermain Lee's bag." "She was the intended target the whole time?" "Yes." "Right." "The PM's visit has obviously been cancelled." "An officer from Central Command is coming to lead the investigation into Hannah's death." "When he arrives, I want you to give him a full briefing." "No." "I'm sorry?" "No." "You're wasting time." "We are wasting time discussing this, and we'll certainly be wasting time briefing another officer to get him up to speed." "MI5 created this new structure." "Don't you believe in it?" "We can deal with this." "All we need is time." "How long?" "Five and a half hours." "Five and a half. 330 minutes." "You sound very sure." "I am." "All right." "That's how long it'll take me to find somebody in long trousers anyway." "Get on with it." "Oh, God, what did I just say?" "That's the Director of Field Operations." "Hannah's dead and I just backchatted her." "Not sure I can take much more of this." "Just while we're on it, why not six hours?" "Or, I dunno, longer?" "She wouldn't have given it to us." "Five and a half put her on the back foot." "She was thinking more about the "half" than the "five"." "Why would somebody shoot her?" "Why did he do that?" "OK, what have we got?" "Danakis..." "I don't think blowing off another toe will get much more out of him." "He only supplied the weapon." "To Jermain Lee, who can't talk now either." "There is the other guy from the warehouse." "Flynn Dixon - if he is the broker, he's done the deal with somebody." "Find him we can follow the money trail." "We can't find him." "That's the problem." "You need medical attention." "You can't check use your real name, they'll nab you." "What do you do?" "We checked out other staff." "No IDs were been used." "Who else?" "Whose ID was there and readily available?" "The security guards." "When the heavies came down, they killed the two guards." "Let's find out their names and go back to the hospitals." "Bingo." "Pete Grainger." "One of the security guards." "Went to AE last night then checked into the Wellstone Clinic." "I've heard very good things about that place." "It's the go-to clinic when you've been blown to smithereens with a shot-gun." "Gotta be our guy." "Fancy playing Doctors and Nurses?" "Not again." "I'm here to run a few tests." "Wait..." "What you doing?" "That's got liquid in it!" "That's all right, just relax." "Let the sedative do its job." "Get off me!" "Good to see you've not forgotten your medical training." "Who are you?" "What do you want?" "Get up!" "Stand up!" "Down there." "I'm here to collect what's owed to us." "I hear you're holding the final instalment of Jermain Lee's payment and I want that money now." "Look at me." "You fucking keep looking at me and you'll stay alive." "Where's the money?" "I haven't got it." "I just set up the deal." "I'm not interested." "I want you to go and get me the remaining fee, plus 50 grand compensation for Jermain Lee's death." "What do you mean" " Lee's dead?" "You've got yourself in way too deep here, Flynn." "His target was an MI5 officer." "They got to Lee and they threw him from a building, and my people want compensating." "But I don't have the cash." "There's one number stored in this phone." "You are going take it, you'll get me the remaining fee plus the 50 grand compensation." "You run... ..you die." "Tracking device is in the phone - you should be receiving the signal." "The rest of the team are en route for backup." "Charlie, will you stop bloody pacing?" "!" "Sorry." "One hour and 42 minutes till we have to report back to Yates." "All units stay tight on Flynn Dixon." "He'll take us to whoever commissioned the hit on Hannah." "We got trouble." "What the hell are you doing here?" "!" "Getting my balls squeezed by Jermain Lee's people." "They're demanding extra money for his death." "What?" "!" "We've gotta go back to them with something - they're not messing about!" "They say we didn't give them enough information about the target." "Who've you been talking to?" "Oh!" "You fucking idiot." "You've brought them here, haven't you?" "I've got a problem" " MI5." "They've come for me." "Get them off my back." "I need an intercept team." "Target's in Longford Arcade." "We play this low-key." "We can't afford any civilian casualties." "We surround the target, take him when it's appropriate." "This is stating the obvious, but it's vital we take him alive." "He's our only link to Hannah's death." "Target heading upstairs." "Anyone got visual?" "Shit...!" "Do whatever you have to." "Just get him alive." "We've lost him." "Armed officers!" "keep back!" "Put your weapon on the ground!" "I'm an ex-MI5 officer." "You don't know what you are getting in to." "We know a lot more than you think." "I doubt that." "I advise you to walk away now!" "Place your weapon on the ground and lie face down." "No way!" "Oh, God...!" "Hannah and Mayhew had history together, personal and professional." "I know he paid her a visit here last night." "You think this was personal?" "Seeing as you didn't bring him in alive, we'll never know." "I certainly intend to find out." "This brings me the issue of Hannah's replacement." "Rachel." "She's the obvious choice." "Luckily, it's my choice." "And I don't do obvious." "Then..." "No." "No." "I mean, I'm not..." "You need someone tougher." "You stood up to me." "Some might say that requires a certain level of steel in the balls." "The others..." "Good." "That's a start." "Referring to them as "the others"." "If it makes you feel better about it then we can put "interim"" "in front of your job title?" "I do feel better with "interim", actually." "Interim team leader." "Never forget that, though." "You have a good team." "I'm relying on you, Charlie." "What do you reckon?" "I'd be lying if I said I'm not pissed off it I can't boss you about." "Yeah, but you don't need a promotion to do that." "But I'm not pissed off it's Charlie." "I'm pleased." "Better the geek you know, right?" "Yes, but we don't exactly know him though, do we?" "If I'm gonna take orders from someone..." "I've gotta respect them." "I want us to find Hannah's killer." "More importantly, I want to find out why she was killed." "Everyone involved is dead apart from Flynn so I reckon we go back to him and shake him about a bit more." "News came through while you were with Yates." "Flynn's dead." "Topped himself before we could ask a single question." "Somebody got to him as well." "Every possible tongue has now been silenced." "So what now?" "Charlie Green?" "You know my name?" "Hannah asked me to give you this." "She was killed today so unless something weird is happening...?" "She asked me to give it to you if she died." "That makes me curious about who you are." "An old friend." "I don't know what this is." "I don't want to know." "I'm just doing what Hannah asked." "Now I have, I'm done." "Subtitles by Red Bee Media Ltd" "Email subtitling@bbc.co.uk" "'Authorities have commenced the mass evacuation of London.'" "Didn't anyone tell you?" "New world, new rules." "Vik, Jez, report, please?" "Who the hell are you?" "Charlie Green." "He's the final member of Field Office 19." "Hannah is the best person you'll ever work for." "You all live here together then?" "Except Jez." "Actually where is he?" "He's done his disappearing act." "GUNSHOT" "Hannah!" "Interim Team Leader." "I'm relying on you, Charlie." "Hannah asked me to give it to you if she died." "This programme contains some strong language and some scenes of a sexual nature." "TAPS ON DOOR" "Oh, shit!" "I've got to go." "We should go out some time?" "Are we allowed?" "What if someone sees us together?" "No-one will see us if we go out of town." "What would they do to you, if they found out about us?" "They wouldn't be happy." "It's against the rules, is it, shagging an informer?" "Just a bit." "So why are you doing it?" "Cos you've got beautiful eyes." "Come Saturday, we'll go out, get off our faces." "I'll see you later." "DOOR CLOSES" "In the event of a terrorist attack, the security alert system will send a warning to all phones and computers in the target area." "The message will advise you of the best course of action to take." "If you are instructed to evacuate..." "Where have you been?" "You're late." "I had to see an asset." "Where's the new boss?" "With Yates." "Obviously not taking his new role lightly." "It looks like he's been here half the night." "You've got some pretty big shoes to fill." "Feeling confident?" "Yes, I think so." "I'll try my best." "I'm actually more confident than that sounded." "You have the ability, I wouldn't have chosen you otherwise." "Right." "What about the investigation into Hannah's death, any progress?" "It's just I was thinking there must be several lines of enquiry..." "It's all in hand at Central Command." "I need you to focus on Field Office 19." "Nothing more." "But as we were handling the initial investigation..." "This is how it works."
