"There's every chance the virus will mutate." "No!" "The human race could be utterly extinguished." "She's a miracle, a walking vaccine." "We knew about the virus before the crisis." "Why didn't you warn us?" "The virus is spreading through the birds." " We'll all get it, won't we?" " You think I'm tough?" " I think you're perfect." " Thank you." "She looked beautiful." " Why now?" " Now it's all there is." ""Hope never dies"." " This will lead to some marketing thing." " Yes, selling what?" " Do you know who else was on the flight?" " The chosen few." "The saved." "Who chose them?" "Who chose you?" "A new beginning, James." "Hope never dies." "I'm going back to the lab, but this time on my own terms." "Something's happened." "The virus finally broke through their defences." " What's your name, son?" " Peter Grant." "I know some people who've been looking for you." "Abby!" "Peter!" "Abby, wait!" "Abby!" " Where did they go?" " Who?" "Who is it?" "Whitaker!" "He had Peter with him." "Are you sure it was him?" "Peter?" "I know my own son!" "If he's here, we'll find him." "She hasn't seen Peter in a long time." "None of us even knows what he looks like." "Do you think she's having some kind of a breakdown?" "She sees a couple of strangers, decides it's Whitaker and Peter?" "Maybe coming back here was a mistake." "It's been too much for her." "There's food, a fire." "Someone was here recently." " Do you recognise anything?" " I should have stayed at the lab." "I should have let Whitaker do whatever he wanted to do." "Better me than Peter." "Stop talking like that." " But he could be anywhere." " He won't go far." "He's waiting for everyone in the lab to die." "We won't have to look for him." "He'll come to us." " Anything?" " No." "Better find out what happened in there." "Wait here." "It's safer for me." "Don't hurt me, please." "Please." "What happened here?" "The virus." "When you came, you infected Jill Whitaker." "Well, how do you know it was me?" "They didn't catch it from the birds?" "The virus has already mutated?" "People are dying who were immune before." "Peter was brought here a few weeks ago." "I did the tests myself." "You're right." "He's like you." "If you tortured him...!" "He's fine." "I tested his blood, that's all." "When the virus infected the lab," "Whitaker told us that he wanted to see the outside world one last time." "He took Peter with him." " Why aren't you dead?" " I'm immune." "I didn't know." "I thought I was gonna die." "I was so scared." " Where's her kid?" " Tom!" " I haven't seen him for weeks." " Let her go!" "You're all at risk." "You need me." "Tom, she's right, we need a vaccine." " What are you gonna do with that?" " What d'you think?" "Violence isn't the answer." "Well, sometimes it's the only way to get things done, and you know it." "Don't tell me what I know." "You really think strangling Fiona Douglas is going to help anything?" " Promise me you won't touch her again." " Why do you care what happens to her?" "I care about what happens to us, what kind of people we've become." "You need to grow up, Anya." "This isn't your nice middle-class world any more." "This is the Dark Ages." "You get your retaliation in first or you don't survive." "You really don't get it, do you, Tom?" "I wouldn't live like that." "I can't be with someone who hurts people." "I'm serious." "I'd kill anyone that hurt you." "It's me, open the door." "How long are we staying here?" "Not long." "I'll cook us some dinner." "Beans or soup?" "Why are these people are looking for us?" "Now, your immune system's response to the virus, it makes you very special." "They want to hurt and exploit you because of that." "But why would they hurt me?" "Some people will do anything to get what they want." "When you came here," "I told you I'd protect you." " Remember?" " Why?" "Why are you doing all this for me?" "I was a friend of your mother's." "Tell me something, how could you just leave your friends and family to die?" "I chose life." "Don't tell me you wouldn't have done the same thing." "I've done terrible things." "I know that." "But it has always been about finding a cure." "If I can do that, don't you think I deserve some credit?" "How does the vaccine work?" "Most flu vaccines target the H and N proteins." "H1N1, so on." "But we have been working on something that provokes the immune system by attacking the M2 protein." "M2?" "The common factor in all flu viruses." "Unlike H and N, it is always the same." " So, what makes Abby so special?" " Her immune system responded by producing antibodies that recognise the M2 protein and beat off the virus." " That makes her unique." " Apart from Peter." "Abby gave us the final piece of the jigsaw." "When she came here, everything fell into place." "I have been working on it night and day since and I am certain that I've got it right this time." "All we have to do now is test it." ""38, 22, 95"." " Will you be OK?" " I can look after myself." "It must have been hard for you, these past few months." "Living rough isn't so bad." " Where are you going?" " If anyone comes, all you have to do is take off the safety catch... then fire." "I don't wanna hurt anyone." "They'll hurt you if they catch you." "Do you understand?" " She's making a fool out of you." " Who?" "Fiona Douglas." "It must be hard being you, Tom." " Why's that?" " All you see is... darkness, hatred, lies." "People are capable of much more than that." "I just see things for what they are." "What do you want?" "I want you." "Close the door." "You know who I am, what I am." "I won't change." "Better to stop now before we hurt each other." "James, I've been waiting for you." "Sorry." "There were complications." "The lab's been contaminated." " And you?" " Well, I'm fine, as you see." "I have the boy." "Can you continue your work with the vaccine?" " Yes, but not here." " Well, then, we must get you out." "I'll prepare an evacuation team." "Shall we say... 10am the day after tomorrow?" " It has to be sooner." " We have to take precautions, James." "You'll be bringing the disease with you." "I told you, I'm not ill." "We can't afford to take risks." "definitely a link between..." "Ah!" "Who were you talking to?" "Who's Landry?" "Tell me where he is." " Abby..." " Tell me." "Kill me and you'll never see your son again." "It's just bruising." "You'll be fine." "My head aches." "Give me my son." "I can't do that." "You're not getting out of this room until you tell us where he is." "Are you immune to the virus?" "Why haven't you been infected?" "Fiona Douglas prepared an antiserum from Abby's blood." "It's not a vaccine but it offers adequate protection in the short-term." "So, when it runs out, you die?" "You should think about that." "He'll tell us." "He doesn't want to die in there." "Of course we knew Whitaker was reporting to someone." "PSJ is... was a big company." "But we assumed they'd all died of the virus." "You thought you were on your own here?" "And you have no idea who this Landry is?" "I've never heard of him." "Give me some minutes alone with Whitaker, I'll find Peter for you." " I won't be party to torture." " You haven't lost your son." "Abby, please, I know what you're going..." "No, you don't!" "You have no idea!" "We're not animals." "I want to take a look around with Abby." "Might get lucky." " You gonna be all right?" " Fine." "This must be where Whitaker was hiding out." "So?" "He's gotta be hiding Peter somewhere nearby." "Come on." "I'll check things this way" " if you want to take a look down there." " OK." "Peter." "Peter Grant." "Peter." "Peter." "Peter?" "Peter?" "Peter." "Peter, it's Mum." "Peter!" "Peter Grant!" "This is hopeless." "Let's just keep looking." "Did you mean what you said?" "About making Whitaker talk?" "I don't care what you do to him." "Just get me my son." "How you doing?" "What do you want?" "I want the boy." "You're gonna tell me where he is." "Like I said, you're gonna tell me." "He hasn't said anything yet." "Peter's all he's got." "He's not gonna give him up that easily." "Only a matter of time." "We were always afraid the virus would mutate in the bird population." "We tested for it constantly." "The vaccine had to protect against any variant." "So, what happened when you tested it before?" "All the volunteers died." "Volunteers?" "To begin with, their immune systems responded magnificently." "I have strengthened the vaccine for a more consistent response." " We have to test it again." " I nominate you." "If something happens, we need her." "Well, it can't be Whitaker." "Not until he tells us where Peter is." "So, it has to be one of us." "Abby already has total immunity to all forms of the virus." "I'll do it." "I'm a doctor." "I can study the symptoms more effectively." "When you're dead?" "Not her." " You can't speak for me." " It's not gonna happen." "I'll do it." "No." "It'll be all right, Naj." "It's gonna work, isn't it?" " I hope so." " There you go." "She hopes so." " No room for doubt there." " Al, if this is because of Sarah..." " I'm fine." "Let's move forward." " No, you're not, you're grieving." "You're volunteering for all the wrong reasons." "Yeah?" "So, what are the right reasons?" "We're all on a ledge here, someone's got to jump off." "We'll inject you with the vaccine first." "There shouldn't be any side effects." "Let's do it." "Hurry, hurry, hurry, hurry." "Faster!" "Come on!" " Whitaker." " Come on, come on." "You're stupid." "Would you rather it was Greg?" " Or Anya?" " You're gonna die... like Sarah." "Everyone I love dies." "I have to do this... so there won't be any more Sarahs." "I need you to understand that." "Of course I understand." "Do I look thick or something?" "You're doing it cos you think you haven't got anyone." "You have." "You've got me." "You'll start displaying symptoms within a few hours of injecting the mutated virus." "Headache, faintness, dry mouth, fever." "At that point, the vaccine will kick in." "His recovery should be... almost immediate." "Are you sure?" "See you on the other side." "Good luck." "I don't feel too clever." "The mutated virus is attacking your immune system." "You're on schedule." "Good to know." "So this is what it's like." "It's too hot." "Al?" "Al!" "This shouldn't be happening." "Do something." "There's nothing I can do." "We just have to wait." "What's wrong?" "Is the vaccine working?" "We won't know until he wakes up." "If he ever does." "Sarah..." "He's back." "Al..." "Al!" "Can you hear me?" "Water." " How do you feel?" " Give him a minute." "We have to know if the vaccine is working." "If it isn't, this is just a temporary reprieve." "His temperature is dropping." "There are no visible signs of the virus." "Oh, my God!" "I think the vaccine works!" "You have no choice." "You have to give us Peter or you don't get out of here." "And if you don't let me go, Abby never sees her son again." "Stalemate." "I'm sure we can find a way forward." "Hope never dies." "You knew?" "But why did you stay behind?" "I, er... got held up." "Didn't get to the airfield." "That was where I was supposed to go, wasn't it?" "I'm sorry." "I must have misunderstood you." "What does this mean?" "It's just a postcode." ""Hope never dies"." " Tell me what it means." " It's just a form..." "Why did I get a card?" "I've no idea." "I'll see you later." "What did it feel like, being almost dead?" "I don't know." "Don't remember." "I didn't see God, if that's what you're fishing for." "He looked after you, though." "Someone did." "You try." "Now, first rule... don't point it at me." "And again." "Try again." "I hit it!" "Give me that." "Leave him alone." " I'm teaching him how to defend himself." " You're teaching him how to kill." "Go inside." "What sort of life do you think he's gonna have now?" "Hm?" "If he can't fight for himself, he'll die." "You know what I dream about, Tom?" "A future where things get better." "But every time I look at you, I can feel it just slipping away." "Fiona." " But I thought..." " That I was dead?" "I should be." "But I'm immune." "You could have shared the antiserum." "But you stole it, all for yourself." "In a few days, the serum will wear off." "You won't be immune any more." "After what you've done, I should let it happen." "You're taking the boy to Landry, aren't you?" "Today, if I can." "I've tested the vaccine." "It works." "Congratulations." "We need 21st-century technology to turn it into an effective immunisation programme." "Can Landry provide that?" "He's the only person who can." "I want in." "I want to come with you, to Landry." "Can you get me the vaccine?" "You think I'm just gonna hand it over?" "Once you've got it, you won't need me any more." "You'll betray me." "I'm sorry you think that." "All the knowledge I need to make the vaccine is up here." "And that's where it stays until you get me safely to Landry." "Whitaker told me the virus started in China." "They never said that on the TV." "Maybe they didn't know." "The PSJ did." "How did they get hold of it months before any health organisation, any government, any journalist?" "And why didn't they say anything?" "My family disappeared off the face of the earth." "But what if Natalie knew?" "Maybe it wasn't me they were running from." "Maybe it was the virus." "Once this is over, Fiona and I are going to take the vaccine on the road." "I'm a doctor." "I should be helping people." "That's my job." "There's a reason..." "I was spared." "This is it." "I'm gathering you don't want me along for the ride?" "I don't think we could ever be happy together." "Because you're gay?" "Because... because we're not the same... and we never can be." "You want me, I know you do." "That's not enough." "What kind of future could we have together?" "There is no future." "It's about now, this minute." "Y... y... you told me that." "But we have to believe in something, we have to build on something, otherwise we... otherwise we're just animals, scratching round in the mud." "Animals are happy enough." "We need to end this, Tom." "It's over." "Who are you?" "My name is Greg Preston." " You're Landry." " You're not a PSJ employee, Mr. Preston." "Is that who you are?" "PSJ?" "PSJ was a small part of our organisation." " Where are you?" " That's none of your concern." "Tell me what this means." "Well, I think you must already know." "It's a warning." "The signal you sent to the chosen few, their cue to get out before the v... before they were contaminated." "How did you keep it a secret?" "Wouldn't you keep silent if your life depended on it?" "How many of you are there?" "Don't try to contact me again." "There'll be no response." "Goodbye, Greg Preston." "Whitaker's gone." " Fiona's missing." " The vaccine?" " Still there, she didn't take it." " They don't need it." "They've got Peter." " They're taking him to Landry." " They can't have got far." " Cars are still here, so they're on foot." " For now." "Abby, Anya, come with me." "We'll check the roads." "Tom, take the woods." " Here." " Hey!" "What about me?" "You should stay here." "You're not well enough." " I'm fine." " No, you're not." "Naj, look after him." "I've got a car ready." "Stop!" "Stop!" "Peter!" "It's OK." "It's me!" "Fiona..." "Peter!" "This is hopeless." "They've gone." "We've lost them." "Tom was right about Fiona." "He was right about everything." "I'm sorry." " It was an accident." " It's not your fault." " I didn't mean to." " It's all right." "You're not to blame." "You, stay there." "Come here, Peter." "It's OK." "I'm a friend." "Don't listen to him." "This is one of the men I told you about, the ones who want to hurt you." " Look what he did to me." " Your mum's alive." "She's here." " I'll take you to her." " That's ridiculous!" "No, you know that's a lie." "Your mother's dead." "She... she's alive?" " She's alive." " He's lying, Peter." "It's a cruel..." "Shut up." "I know you." "You're the man who hijacked Billy's truck." "Billy was nice to me." "You've got it wrong, son." "I'm not gonna hurt you." "I'm your only friend, Peter, the only one who can save you." "Come on, I'll take you to your mother." "It'll only take a couple of minutes..." " Have I killed him?" " Yes." "He shouldn't have lied about my mum like that." "You did the right thing." "Come on, we have to hurry." " Where are we going?" " Somewhere safe." "Any luck?" " The airfield." " What airfield?" "If they're meeting Landry, that's where they'll go." "You don't know that." "The airfield, the postcard, the lab... it all fits." "Anyway, what else have we got?" "We need the vaccine." "Why didn't you tell us about this airfield before?" "We didn't know what it meant." "You really think these people escaped the virus and hid somewhere?" "It looks that way." "Stay here in case Tom gets back." "Tell him where we're going." "Hey..." "I wanna help." "Just stay here... in case we're wrong." "Ahh!" "Uh." "What's that noise?" "What noise?" " What does it mean?" " It means Greg was right." "Come on." "Where are we going?" " To the airfield." " Anya said you should be resting." "If you think I'm gonna stay here, you're crazy." "Are you coming or not?" "He's here." "We're safe." "Don't come any closer, please, James." "We must be careful of infection." "I'm protected by the antiserum." "You might still be a carrier." "We've kept ourselves safe from the virus for so long, it would be foolish to take any risks now." "We've prepared a quarantine section of the plane." "Please restrict yourself to that area alone." "You must be Peter." "You're a very welcome guest, Peter." "I think you'll be happy with us." "Is it true?" "You've got light and power and stuff?" "You didn't get the virus?" "It's true." "We've made ourselves a little paradise, a paradise you can help us protect." "You'll be given every possible luxury while we examine you." " Examine me?" " It's just a few tests." "No." "Peter, come back!" "Peter!" "Mum..." "Mum!" " No, Abby..." " Just stay there, please, Mrs. Grant." "If any of you come any closer, I'll have to kill you." "Listen, we... we've got the vaccine." "Take it." "Just give us Peter." "Well, let him go!" " Put the case down and step back." " The boy first." "Greg, please!" "Check it." "No!" "He won't be harmed." "This is how you did it?" "You... you brought everyone here and then you... you flew them out?" "Well, there were many places like this in many countries, but... yes." "And how many people?" "Hundreds?" "Thousands?" " Enough." " Enough?" "For what?" "To help us to rebuild society when the time comes." "People with the necessary skills..." "leaders, thinkers, planners." "Natalie Preston." "My wife, was she one of them?" "Did she save my children too?" "I'm afraid that name's unfamiliar to me." "She sent me the postcard." ""Hope never dies"." "It had to be her." "You must know." "Have you kept any of the vaccine back for yourselves?" "Enough for ourselves and our friends." "Very sensible." "I'd have done the same in your position." "No, please, please!" "You've got what you want." "Just let him go." "No-one knows yet just how effective this vaccine will be." "Perhaps it'll work, I hope so, but up until then, we need some insurance." "I'm afraid we'll have to borrow your son" " for a little longer." " No!" "We had a deal!" "You made a business proposal, I'm obliged to reject it." "Take me instead." " Abby!" " Take me." "Mum!" "No!" "This is the place." " There's Tom!" " Wait!" "Come here!" "I've no objection to an exchange, Mrs. Grant." "Mum!" "Go with Greg." "You'll be OK." "I'll come back for you, I promise." "Very well." "How did you know about the virus before anyone else?" "What really happened in China?" "It was your fault, wasn't it?" "You did something." "We were testing a genetically engineered virus that would provide a single cure for all forms of flu." "It would have been a blessing to humanity." "Thousands of lives saved every year." "Naj!" "There were... unforeseen interactions with the human immune system." "Within days, we... knew a pandemic was inevitable." "You killed... billions of people!" "It... it was your fault." "We had the very best of intentions." "Peter!" "Let him go!" " Abby, Abby!" " No!" "Hey, hey, hey!" "Listen to me." "Wait here." "Do it!" "Do it!" "Do it!" "Argh!" "I'm sorry." "I couldn't." "It's OK, Naj." "It's OK." "You guys stay here." "Keep hold of the boy." "You can't just let them go." "Let him go!" "Let Peter go!" "Take the vaccine." "The boy stays." "The vaccine will be mass produced, everyone will be provided for." "You have my word." "Mum!" "Mum!" " I'm sorry." " It's OK, it's OK." "It's OK, you're safe." " Anya!" " Naj!" "Anya." " What are you doing here?" " We couldn't just sit around." "Hey, Peter!" "Nice to meet you at last." "Hey..." "Do you think he was lying about your wife?" " Didn't she send you the card?" " I don't know." "Come on." "Let's get going." "We should find Tom." " He was just ahead of us." " He was here?" "He was in the control tower, took out the gunman." " Well, where is he, then?" " I dunno." "He was shot." " Shot?" "!" " He was OK, though, he was on his feet." "He... he might have collapsed somewhere..." " Anya, it's OK." "Tom, he'll be fine." " He's probably just resting up." "We have to find him." "Tom!"
