A young woman calls to ancient spirits in order to right the wrongs inflicted on her. For this she summons the mythical beast that has long been rumored to roam the verdant forests. Nearby, a young man readies a cabin for the arrival of his friends. They've been coming to this place every year since they were kids, to relax and shape up before the start of a new college year. Only this time, they're about to meet their worst nightmare.
