Matt Simmons, a man struggling with his traumatizing past, is in rehab at a small summer camp out in the middle of nowhere. Not knowing anyone there, and not wanting to be there, Matt spends most of his time cooped up in the dorm away from people. But a series of events will force him to confront his past and convince the camp director of a deadly predator in the area before people start to die.
