A corporate team from a pharmaceutical company sets out to conquer a remote mountain, intending a straightforward climbing expedition that should strengthen their bonds. What awaits them at the summit shatters every assumption about safety and civilization. Intelligent, coordinated monkeys don't just inhabit this peak: they actively hunt the climbers with unsettling purpose and strategy. The group fragments under pressure as trust erodes and the environment becomes increasingly hostile. Survival hinges on understanding the monkeys' behavior, but the animals seem to operate with a logic that defies natural explanation. Each decision to push forward or retreat carries lethal consequences, and paranoia creeps in as the team questions whether they're facing mere beasts or something far more calculated. What begins as an office-building exercise transforms into a psychological thriller where the mountain itself becomes a character. Alliances crumble, secrets spill out, and the distinction between predator and prey blurs in ways no one expected. This isn't your standard wilderness survival story: something about this place and these monkeys demands answers the climbers desperately need before it's too late.
