Searching for a cure to Alzheimer's disease a group of scientists on an isolated research facility become the bait as a trio of intelligent sharks fight back.

Preacher: Einstein's theory of relativity. Grab hold of a hot pan, second can seem like an hour. Put your hands on a hot woman, an hour can seem like a second. It's all relative.
Tom Scoggins: I spent four years at CalTech, and that's the best physics explanation I've ever heard.
Preacher: Ooh, I'm done! Brothers never make it out of situations like this! Not ever!
Preacher: Yea, though I walk through the valley of the shadow of death, I shall fear no evil. For thou art with me. Thy rod and thy staff, they comfort me. Surely goodness and mercy shall follow me all the days of my life. Because I carry a big stick and I'm the meanest mother fucker in the valley! Two sharks down, Lord! One demon fish to go! Can I get an Amen?
Preacher: We will start with the perfect omelette which is made with two eggs not three. Amateurs often add milk for density; this is a mistake.
Carter Blake: That's the answer to the riddle. Because that's what an 8000 pound mako thinks about. About freedom. About the deep blue sea.
Tom Scoggins: They're big, real big.
Carter Blake: What's that?
Tom Scoggins: The size of your brass balls!
[Regarding last shark]
Dr. Susan McCallister: We have to kill her.
Carter Blake: That's the smartest thing you've said all day.
Preacher: I hate to interrupt this moment of burgeoning intimacy but can we get the fuck out of here?
Tom Scoggins: Come on, Jan was a healthy girl she must've had something that run on batteries.
Preacher: Nice.
Tom Scoggins: Where would a girl keep her... rrrrrrrn... thing?
Preacher: Hey, what's the matter with you?
Russell Franklin: So here's the riddle. What does an eight thousand pound mako shark with a brain the size of a flat head V8 engine and no natural predators think about?
Carter Blake: Well, I'm not waiting around here to find out!
Russell Franklin: You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... and only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.
Dr. Susan McCallister: [after slashing her hand to use the blood as bait] She may be the smartest animal on the planet, but she's still just an animal. Come to mama.
Preacher: [to Carter who has his feet in the water] Let me ask you something, are you sure it was just three sharks?
Carter Blake: Yeah.
Preacher: Oh. Okay.
Preacher: [Carter takes his feet out of the water] That's more like it.
Carter Blake: A 45-foot shark, and you hit me. Nice.
Preacher: Shit, it could've been worse. I could've let him eat your ass.
Preacher: I'm not Daniel when he faced the lion. So I appreciate the irony, Lord! Cook dies in his own oven! But I've got other plans!
Preacher: [jumps out of upper oven and swims away, lights lighter] You ate my bird!
[throws lighter into open oven and blows up the shark]
[last lines]
Carter Blake: Let me tell you, man. I quit this job.
Preacher: Take me back to the ghetto.
Carter Blake: Amen.
Preacher: You're the guy that got caught in that avalanche, right?
Russell Franklin: Yeah, I'm the one.
Preacher: Like black men don't have enough ways to get killed without climbing up some stupid ass mountain in the middle of God's nowhere! You leave that to the white folks! Brother!
Dr. Susan McCallister: You wait your whole life for a single moment and then suddenly it's tomorrow.
Tom Scoggins: Now you see how that works? She screwed with the sharks, and now the sharks, they're screwing with us.
Janice Higgins: Beneath this glassy surface, a world of gliding monsters!
The Parrot: Eat me, asshole.
Janice Higgins: There's doctor Jim Whitlock, the most brilliant man ever!
Russell Franklin: He's pissing into the wind! How brilliant can he be?
Janice Higgins: You'll see!
Preacher: All right, all right, all right. Okay, okay, okay. If this is a lesson about the drinking, let's just say I've learned.
[Sherman drops the bottle]
Preacher: Don't need to get all carried away, showing me your vengeful side. I know your wrath, Lord!
Preacher: Carter!
Carter Blake: Hey.
Preacher: Bring me some sushi.
The Parrot: Fat butt... you got a big fat butt!
Preacher: Any of your nonsense and we're gonna have tiny little drumsticks on the menu tonight.
Preacher: [talking to shark] You ate my bird!
Carter Blake: No, what you've done is taken God's oldest killing machine and given it will and desire. What you've done is knocked us all the way to the bottom of the goddamn food chain. It's not a great leap forward in my book.
Carter Blake: They got a pill for what's wrong with you?
Tom Scoggins: Who're you gonna trust?
Carter Blake: You?
Tom Scoggins: That's right, you trust me!
Russell Franklin: Was that a goddamn shark broke through that door?
Carter Blake: I expect so.
Russell Franklin: You expect so? Huh. Well, well, well. Am I the only asshole down here who thinks that a tad bit odd?
Russell Franklin: It can do that? Bust through a steel door?
Russell Franklin: What in God's creation?
Jim Whitlock: Oh, not His. Ours.
Dr. Susan McCallister: Tell me Mr. Franklin, have you ever known anyone with Alzheimer's?
Russell Franklin: Well, no.
Dr. Susan McCallister: By the end all my father could do was ask why my mother wasn't at home, and each time I told him she was dead I had to watch him take that loss like a car wreck. 200,000 men and women develop Alzheimer's each year! What if you could end all that suffering with a single pill? Give me till Monday morning, 48 hours. I'll give you results that'll skyrocket your stock price or I'll help you pack the lab myself. It's your call.
Preacher: Man I hate this song.
Brenda: Like the tunes Preach?
Russell Franklin: Hey, an AGA mask! Did some wreck diving in one of these off the coast of Spain. Tourist thing, you know. You like wreck diving?
Carter Blake: It's okay.
Russell Franklin: Come on, I bet you're really good at it!
Carter Blake: We're on the water. Whole cat-and-mouse thing don't float. You're the man, right?
Russell Franklin: Yeah. Yeah, I'm the man.
Carter Blake: Well, the man's always got a file. What's it say?
Russell Franklin: Two years, Leavenworth, smuggling.
Carter Blake: How'd you make your money? You're the first rich guy in history who's squeaky-clean?
Russell Franklin: You do understand my concern, right?
Carter Blake: Look, I got a workable deal here. I don't make waves, I meet the terms of my parole. I'm not out to change the world like the doc, and I'm not out to wreck it either.
Russell Franklin: Just what the hell did you do to those sharks?
Dr. Susan McCallister: Their brains weren't large enough to harvest sufficient amounts of the protein complex. So we violated the Harvard Compact. Jim and I used gene therapies to increase their brain mass. A larger brain means more protein. As a side effect the sharks got smarter.
Janice Higgins: You stupid bitch!
Sherman "Preacher" Dudley: You weren't the sunny kid in your class, were you?
Carter Blake: I never went to class.
Russell Franklin: Well I'll be damned.
Jim Whitlock: No, Mr.Franklin you've just seen what it like *not* to be damned.
Dr. Susan McCallister: We're this close to the reactivation of a human brain cell.
Tom Scoggins: Who you gonna trust huh? You trust me. You know why? Because I'm *Trustworthy*
Jim Whitlock: You did it, pal, you did it...
