In 2018, a mysterious new weapon in the war against the machines, half-human and half-machine, comes to John Connor on the eve of a resistance attack on Skynet. But whose side is he on, and can he be trusted?

[from trailer]
Marcus Wright: What day is it? What year?
Kyle Reese: 2018.
Marcus Wright: What happened here?
Kyle Reese: Judgment Day happened.
John Connor: The devil's hands have been busy. What is it?
Kate Connor: It's real flesh and blood, though it seems to heal itself quickly. The heart is human and very powerful. The brain, too, but with a chip interface.
Marcus Wright: What have you done to me?
Kate Connor: It has a hybrid nervous system. One human cortex, one machine.
Marcus Wright: Blair, what have they done?
John Connor: Who built you?
Marcus Wright: My name is Marcus Wright.
John Connor: You think you're human?
Marcus Wright: I am human.
Dr. Serena Kogan: Welcome home, Marcus. We knew you'd be back. After all, it was programmed in you. Oh, and you executed that programming beautifully.
Marcus Wright: What am I?
Dr. Serena Kogan: You are an infiltration prototype. The only one of your kind. Advanced Cyberdyne's work, we resurrected you, amended it.
Marcus Wright: You're dead.
Dr. Serena Kogan: Calculations confirm Serena Kogan is the

John Connor: easiest for you to process. We can
[transforms into Kyle Reese]
Kyle Reese: be others if you like. Marcus, what else could you be... if not machine?
[transforms back into Serena Kogan]
Marcus Wright: A man.
Dr. Serena Kogan: The human condition no longer applies to you. Accept what you already know. That you were made to serve a purpose. To achieve what no other machine has been able to do. To infiltrate, find a target and then bring that target home to us.
[flashback recording from Marcus' perspective]
John Connor: We've been at war since before either of us even existed. You tried to kill my mother, Sarah Connor.
Dr. Serena Kogan: In times of desperation, people will believe what they want to believe. And so, we gave them what they wanted to believe. A trick in the form of signal the Resistance thought would win the war. And they were right, it will end this war. Except that it is the Resistance that will be destroyed. Not, Skynet. Our best machines have failed time again to complete a mission. Something was missing. We had to think, radically. And so we made you. We created the perfect infiltration unit. You, Marcus. You did what Skynet has failed to do for so many years. You killed John Connor. Don't fight, Marcus. Remember what you are.
Marcus Wright: I know what I am.
[rips out computer chip, crumbles]
Marcus Wright: I'm better this way.
Dr. Serena Kogan: You will not be given a second chance. You cannot save John Connor.
Marcus Wright: Watch me.
[from trailer]
Kyle Reese: Come with me if you want to live.
[last lines]
Marcus Wright: [thinking] What is it that makes us human? It's not something you can program. You can't put it into a chip. It's the strength of the human heart. The difference between us and machines.
John Connor: [pause]
[continues thinking]
John Connor: There is a storm on the horizon. A time of hardship and pain. This battle has been won, but the war against the machines races on. Skynet's global network remains strong, but we will not quit, until all of it is destroyed. This is John Connor. There is no fate, but what we make.
John Connor: [from trailer] We've been fighting a long time. We are out numbered by machines. Working around the clock,without quit. Humans have a strength that cannot be measured. This is John Connor. If you are listening to this,you are the resistance.
Marcus Wright: If you're going to point a gun, you'd better be ready to pull the trigger.
Kyle Reese: [later, repeating Marcus] If you're going to point a gun, you'd better be ready to pull the trigger.
John Connor: This is John Connor. If you're listening to this, you are the resistence. Listen carefully, if we attack tonight, our humanity is lost. Command wants us to fight like machines. They want us to make cold, calculated decisions. But we are not machines! And if we behave like them, then WHAT IS THE *POINT* IN WINNING? Command is going to ask you to attack Skynet. I am asking you not to. If even one bomb drops on Skynet before sunrise, our future will be lost. So please stand down. Give me time to protect the future that all of us are fighting for. This is John Connor.
John Connor: Skynet has Kyle Reese.
General Ashdown: Then that is his fate.
John Connor: No, it's our fate. I have to save him. He is the key. The key to the future, to the past. Without him, we lose everything.
General Ashdown: No, you stay the course!
John Connor: If we stay the course, we are dead! WE ARE ALL DEAD!
General Ashdown: As of this moment, soldier, you are relieved of your command. You are no longer a part of this Resistance.
[Ashdown switches off comm]
Barnes: I didn't catch that last statement.
Comms Officer: Neither did I.
[from trailer]
John Connor: I knew it. I knew it was coming. But this is not the future my mother warned me about. And in this future, I don't know if we can win this war. This is John Connor.
Marcus Wright: Everybody deserves a second chance... this is mine
John Connor: [to Marcus] You and me, we've been at war since before either of us even existed. You tried killing my mother, Sarah Connor. You killed my father, Kyle Reese. You will not kill me.
Kate Connor: What should I tell your men when they find out you're gone?
John Connor: I'll be back.
John Connor: Connor, get your ass topside. Remind those men they need to answer me on the radio, even if they are dead.
John Connor: What *are* you?
Marcus Wright: I don't know.
Marcus Wright: [Kyle is eating something] What is that?
Kyle Reese: Two day old coyote. It's better than three day old coyote.
Kyle Reese: [a car radio suddenly starts and Kyle hears music for the first time] What is that?
Marcus Wright: Something my brother used to listen to.
Marcus Wright: So that's what death tastes like.
[after Marcus helps John defeat the Hydrobots, John Connor turns and points his gun at him]
John Connor: They know what you are, even if you don't.
Marcus Wright: Enough! That gun ain't gonna stop shit!
John Connor: Nobody's shot you in the heart, and I see that thing beating a mile a minute!
Marcus Wright: [Suddenly cautious] Kyle Reese. He's in Skynet. You do that, he's dead. I can get you in.
John Connor: [pauses] How?
[Marcus steps forward into the light. His face is half-mangled, revealing a metal skull underneath]
Marcus Wright: Look at me.
John Connor: That's why I don't trust you.
Marcus Wright: I'm the only hope you have.
[pauses]
Marcus Wright: I need to find who did this to me. So do you.
[first lines]
Dr. Serena Kogan: Marcus. How are you?
Marcus Wright: Ask me in an hour.
John Connor: Why'd you do it?
Blair Williams: I saw a man, not a machine.
Dr. Serena Kogan: Don't fight, Marcus. Remember what you are.
Marcus Wright: I know what I am.
[tears out hardware link from his cortex]
Marcus Wright: I'm better this way.
Dr. Serena Kogan: You will not be given a second chance. You cannot save John Connor.
Marcus Wright: Watch me.
General Ashdown: Connor, tell me it works.
John Connor: It works! That is affirmative. The signal works.
General Ashdown: Good. The attack commences tomorrow at 0400 worldwide. Your unit will be in support of the bombing of Skynet Central.
John Connor: What is the extraction plan for the prisoners?
General Ashdown: Extraction plan? There *is* no extraction plan. We're gonna level the place.
Barnes: Huh?
John Connor: Negative! I told you, Skynet Central is *filled* with human prisoners!
General Ashdown: [sternly] This is war, Connor. Leadership has its costs. You, above all, should know that.
John Connor: Who built you?
Marcus Wright: [Held suspended in chains] My name is... Marcus Wright.
John Connor: You think you're human.
Marcus Wright: I am human.
[Connor steps forward, releases the chain holding Wright's head up, and looks down at his chest. Wright looks down at himself]
Marcus Wright: Noooooo!
[Horrified]
Marcus Wright: Nooo! Ahhhhhh!
[struggles against the chains]
John Connor: Where were you manufactured?
Marcus Wright: I was *born*. August 22, 1975.
[Screams again and fights against the chains, then looks at Connor]
Marcus Wright: I know you. I heard your voice on the radio. You're John Connor.
John Connor: Of course, you know me. You were sent here to kill me.
Marcus Wright: I don't know what you're talking about.
John Connor: Then why are you here?
Marcus Wright: Blair said you could help me find who I'm looking for.
[pause]
Marcus Wright: Now let me down.
John Connor: If I let you down, you'll kill everyone in this room.
Marcus Wright: [with one shake of his head] Just you, Connor. I didn't even know your name until two days ago.
John Connor: No. You and me. We been at war since before either of us existed. You tried killing my mother, Sarah Connor. You killed my father, Kyle Reese. You *will* not kill me.
Marcus Wright: Kyle Reese is no a transporter heading for Skynet. If I wanted to kill him, I would've done him in LA.
Kyle Reese: [to Marcus] You want to know the difference between us and machines? We bury our dead. But no one is coming to bury you.
Kyle Reese: Moto-terminators!
Marcus Wright: Now, let me down.
John Connor: If I let you down,you'll kill everyone in this room.
Marcus Wright: Just you Connor. Because I don't give a shit about you.
John Connor: [to T-800] DO IT! YOU SON OF A BITCH!
[T-800 inflicts scars on John Connor]
John Connor: [points gun at Reese] What's your name?
Kyle Reese: Kyle Reese.
Kyle Reese: John Connor... We gotta find this guy.
[from trailer]
John Connor: Win or lose, this war ends tonight!
