Armed with a camcorder, a circle of friends parties at an abandoned insane asylum where, five years earlier, they caused a young patient's death. But their fun turns to fright when the consequences of their heinous crime catch up with them. Will they get out alive, or are they doomed? And what will the tapes reveal?

A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy. Their concept catches on, with underground "fight clubs" forming in every town, until an eccentric gets in the way and ignites an out-of-control spiral toward oblivion.
