Justine is a freshman at Columbia University who willingly joins an activist group being attracted by its charismatic leader Alejandro. Even despite unfriendly behavior of the group’s leader, Justine is eager to participate in a trip into the Amazon organized in order to protest land developers who are decimating native populations. Upon arriving into the Amazon their protest meets with mixed success, they achieve their goals and hurry up to return home. They quickly turn around their plane and head back to the civilization, but unfortunately their plane crashes. The young people are lost in the juggles and soon intercepted by the very cannibalistic tribe they’ve been defending so persistently. All the survivors are imprisoned in the tribe’s village. They discover that the indigenous world is far more sinister than the civilized one they were trying to protect it from.
