The deadly Amazon rainforest is known as a no-man’s land from which none return. An outdoor guide leads an expedition deep into its interior, yet he is jolted awake by a nightmare the night before — the entire team will end up as prey to giant caimans.
He risks everything to urge the group to retreat at once, only to be publicly mocked as a coward by a wealthy heir. When the rest insist on pressing onward, their escape route is completely cut off by an enraged horde of giant caimans. Their only remaining path leads through the Death Canyon, home to an anaconda den.
Along the way, they encounter a stranded ecologist. Apart from one veteran team member, no one believes the guide’s warnings. The wealthy heir grows increasingly reckless; he detonates explosives to stun fish for amusement and destroys caiman nests, repeatedly dragging the whole team toward doom. One teammate after another is devoured by the reptiles, and a rescue team that arrives is also wiped out by the caiman swarm.
Trapped with no hope of outside help, the guide must rely on his unmatched wilderness survival skills to lead the survivors. They fight to carve out a path to freedom while being hunted relentlessly by both giant caimans and anacondas.
