Justyna, an idealistic college freshman at
Columbia University, becomes deeply passionate about environmental activism after attending a rally led by a charismatic upperclassman named Alejandro. Alejandro and his militant group are planning a high-stakes protest in the Amazon rainforest to halt a ruthless corporate logging company from bulldozing the indigenous Kuiro tribe’s land. Driven by a desperate need to find her own voice and make a tangible difference in the world, Justyna eagerly volunteers to join the expedition, despite quiet warnings from her cautious roommate, Samantha.Upon arriving in Peru, the activists orchestrate a daring, illegal blockade. They chain themselves to bulldozers and stream the entire confrontation live via social media, successfully halting the corporate destruction. However, their triumphant euphoria is short-lived. As their small chartered plane takes off for the return trip, a catastrophic mechanical failure sends the aircraft spiraling out of the sky. It crashes violently deep within the unforgiving, uncharted jungle. Several members die upon impact, while the surviving activists—including Justyna, Alejandro, Jonah, Jonah’s girlfriend Amy, and fellow protester Lars—are left stranded, terrified, and injured miles from civilization.Seeking help, the panicked group hikes deeper into the dense canopy, unaware they are walking right into a nightmare. They are soon ambushed by the Kuiro tribe, who are not the peaceful victims the activists imagined, but a brutally traditional, flesh-eating culture. Captured and dragged to a
remote village, the foreigners realize their ideals mean nothing here. Lars is gruesomely butchered and consumed during a horrific tribal ritual, shattering the group’s morale.Desperate to escape, the captives endure agonizing psychological and physical torment. Internal fractures quickly destroy the group's unity; a terrified Jonah betrays his friends to save himself, only to meet a gruesome fate anyway, while Alejandro’s selfish cowardice is revealed, proving he cared more for social media clout than actual human lives. Justyna, pushed to the absolute edge of sanity, musters a fierce will to survive. When the tribe prepares her for the ultimate ritualistic mutilation, she uses painted markings to blend in and frantically escapes her cage. In a brutal, chaotic climax, she manages to sabotage the village using modern technology and fire, narrowly fleeing into the jungle and finding rescue. Back in New York, a deeply traumatized Justyna is debriefed by government agents. When asked if the cannibalistic tribe still exists, she lies to protect them, choosing to keep her harrowing ordeal a dark secret.
