A charismatic young activist named Alejandro inspires his fellow students with a rousing story about an untouched Peruvian jungle about to be destroyed by a greedy energy company looking to exploit its natural resources. Soon eight young protestors, including Justine, the daughter of a U.N. official, and her roommate Kaycee, are headed to this remote Amazon village to ward off the bulldozers. But when their small plane crashes in the jungle, they are horrified to discover that the tribe they came to save still practices the ancient rite of cannibalism.
