A special military unit fights a powerful, out-of-control supercomputer and hundreds of scientists who have mutated into flesh-eating creatures after a laboratory accident.

[Matt and Spence are helping Rain]
Rain: When I get outta here... think I'm gonna get laid.
Matt: Yeah, you might want to clean up a little bit first.
[Rain and J.D. have just fought off a zombie]
J.D.: I shot her five times. How was she still standing?
Rain: Bitch isn't standing now.
[Alice points her gun at Rain]
Rain: I'm not dead yet.
[Rain takes the gun from Alice]
Rain: I think I'll take this back.
Alice: I could kiss you, you bitch!
Rain: I don't want to be one of those things. Walking around without a soul.
Red Queen: You're all going to die down here.
Rain: Your boyfriend's a real asshole.
Rain: She bit me, man. She took a chunk clean outta me.
Alice: There's a cure!
[to Rain]
Alice: You're gonna be alright!
Rain: I was beginning to worry.
Kaplan: Bitch wouldn't open the door, so I had to fry her.
Rain: That homicidal bitch killed my team.
Alice: That homicidal bitch may be our only way out of here.
Rain: No pressure, guys.
[first lines]
Narrator: At the beginning of the 21st century, the Umbrella Corporation had become the largest commercial entity in the United States. Nine out of every ten homes contain its products. Its political and financial influence is felt everywhere. In public, it is the world's leading supplier of computer technology, medical products, and healthcare. Unknown, even to its own employees, its massive profits are generated by military technology, genetic experimentation, and viral weaponry.
Rain: All the people that were working here are dead.
Spence: Well, that isn't stopping them from walking around.
Red Queen: Even in death the human body still is active. Hair and finger nails continue to grow, new cells are produced, and the brain itself holds a small electrical charge that takes months to dissipate. The T-virus provides a massive jolt, both to cellular growth, and to those trace electrical impulses. Put quite simply, it reanimates the body.
Rain: It brings the dead back to life?
Red Queen: Not fully. The subjects have the simplest of motor functions. Perhaps a little memory, but virtually no intelligence. They're driven by the basest of impulses, the most basic needs.
Mr. White: Which is?
Red Queen: The need to feed.
Red Queen: I've been a bad, bad girl.
Matt: [held down] You can't do this!
Rain: [removing gas mask] Blow me.
Spence: What happened here?
[Alice and Matt both look towards "One" rather anxiously for an answer as well]
James "One" Shade: Five hours ago Red Queen went homicidal, sealed the Hive and killed everyone down here.
Spence: Jesus!
James "One" Shade: When we realized what was happening, my team was dispatched to shut her down.
Alice: Why did she do it?
James "One" Shade: That we don't know, but outside interference is a possibility.
Red Queen: I can give you the code, but first you must do something for me.
Alice: What?
Red Queen: One of your group has been infected. I require her life for the code.
Kaplan: [the team runs towards Rain after hearing gunshots] What was all the shooting?
Rain: We found a survivor.
Kaplan: And you shot him?
Rain: She was crazed. She bit me.
Kaplan: What are they? It's pretty goddamn obvious what they are. Lab coats, badges, THOSE PEOPLE USED TO WORK HERE!
Alice: I'm missing you already.
[the lethal laser bar approaching One becomes an unavoidable lattice]
James "One" Shade: Shit!
Spence: [points the gun at Matt] Please, I wouldn't wanna shoot you. I might need the bullets. Back off!
Spence: In or out? In... or out?
Alice: I don't know what we had, but it's over.
Spence: [a female scientist zombie bites Spence] OH, GOD!
Spence: [Spence shoots the scientist; Matt fights Spence for the gun] Back... the FUCK off!
Spence: [to Alice] I'm missing you already.
[Locks Alice, Rain, and Matt inside the flooded research lab]
Kaplan: You're going to have to work for your meal.
Red Queen: I implore you.
Kaplan: Implore away!
Spence: Nothing - ever - changes.
Spence: [J.D. enters a code to open a secured door] You got it?
J.D.: See how easy that was?
Kaplan: [the door opens only to find a room extremely full of the undead flesh-eating zombies] Shit!
Rain: [yells] J.D., no! Grab my hand and hold it real tight!
J.D.: Don't let me go!
J.D.: [the zombies pulls J.D. back; Rain lets him go] RAIN! FUCK! NO!
[zombies chomping and devouring; J.D. screaming]
[last lines]
Dr. William Birkin: I want her quarantined - close observation and a full series of blood tests. Let's see if she's infected. Take her to Raccoon City facility. Then assemble the team. We're reopening the hive. We want to know what went on down there. Just do it.
Kaplan: [surrounded by zombies, Kaplan contemplates suicide and finds one bullet left in his gun] That's lucky.
Red Queen: The T-virus is protean, changing from liquid to airborne to blood transmission, depending on its environment. It is almost impossible to kill.
Alice: I'm not sure I want to remember what went on down here.
James "One" Shade: I don't blame you.
Mr. Grey: [being pushed] Thank you!
Ms. Black: Some people.
Mr. Grey: Yeah.
Alice: Watch the tank! The tank!
Kaplan: She was right. We are gonna die down here.
Kaplan: [they see the holographic representation of the Red Queen] It's a Holographic representation of the Red Queen, modeled after the head programmer's daughter. Don't listen to anything she says. She's only trying to deceive us... confuse us... she'll say anything to stop us shutting her down.
[letting blood from her wounded hand drip down onto the zombies below them]
Rain: Yeah, you like how I taste, don't you?
Red Queen: Just one bite, one scratch from these creatures is sufficient. And then, you become one of them.
Rain: Why didn't you tell us about the antivirus?
Red Queen: This long after infection, there was no guarantee it would work.
Rain: But there's a chance... right?
Red Queen: I don't deal in chance.
Matt: What the fuck was that?
James "One" Shade: [One is holding one of his dying soldiers] Stay conscious. You're going into shock.
James "One" Shade: [the soldier closes his eyes] Stay awake!
