A scientific expedition sets out for Borneo to seek a flower called the Blood Orchid, which could grant longer life. Meanwhile, they run afoul of snakes and each other.

Cole Burris: I had this friend, who had this friend who shot documentaries, and he and his whole crew went down to the Amazon, and they were all eaten by snakes, and thats a true story
Gordon Mitchell: Come on Cole, you new a guy who new a guy. That's an urban Myth.
[last lines]
Gail Stern: So how much further to my bath?
Bill Johnson: Kotabaru? I'd say... another day downriver.
Cole Burris: Another day? I'm not rowing another day, homeboy.
Bill Johnson: All right. Let's see, we got this shortcut right up -
Sam Rogers, Cole Burris, Gail Stern: No!
Bill Johnson: It's mating season.
Cole Burris: What so you're tellin' me there's some snake orgy going on in the jungle?
Bill Johnson: Yeah, something like that
Gordon Mitchell: Are you okay now?
Gail Stern: Yeah, I'm fine. And keep your hands off of me!
Gordon Mitchell: It might be hard, but I'll try!
Cole Burris: I'm so hungry, I'd sell my Grandmother for a tic tac!
Gordon Mitchell: You mention "food" once more and I'm voting you off this island.
Cole Burris: I might die of a heatstroke, but I'm gonna have a nice, tight ass!
Gail Stern: Can you hear me now? Shit. Can you hear me now? Can you hear me now?
Cole Burris: WE can!
Gail Stern: Can you hear me now?
[Gail plunges into the river]
Gordon Mitchell: Hey Gail, can you hear me now?
Sam Rogers: We're in the middle of the jungle Jack, at this point your authority is what we say it is.
Gail Stern: [seeing Bill's boat for the first time] I've seen subway carts in better shape than this!
[after Sam decapitates an anaconda]
Cole Burris: That's what I'm talking about! That's what I'm talking about, Sam! Oh, my God! You're the bomb! You Lorena Bobbitt-ed that ass!
[to the dead decapitated anaconda]
Cole Burris: How you like that, bitch? She sliced you! Diced you! She cut you up! That was like Sam with the samurai action! Say it now...
[another anaconda snatches up Cole]
Gail Stern: Hey! Over here bitch!
Dr. Ben Douglas: [the expedition is wading through a marsh - Ben starts humming the theme from "Jaws"] Duuh, dum, duuh, dum. Dum dum dum dum dum dum...
Gail Stern: Stop that, or I swear to God I'll kill you!
[Ben gets pulled under the water]
