In 1977, a group of young people were massacred by Sister Mary Chopper at the Happy Day Bible Camp, leaving only two survivors. Seven years later, Father Richard Cummings leads a new group of teenagers to the camp, despite warnings about its dark past. As the bodies start to pile up again, it's revealed that the true killer is Eugene, a goth local with a twisted connection to his abusive past and a penchant for gore. In this hilarious and campy horror-comedy, Father Cummings must confront his demons and face off against a transvestite serial killing nun in a fight to the death.
