In this campy, supernatural horror tale from director Grant Austin Waldman, clueless graduate student Diane (Brinke Stevens) finds her new digs infested with evil demons who promptly possess her -- body and soul. Next thing you know, she morphs into a leather-clad, chainsaw-wielding temptress whose lone chance for redemption rests with a priest (Robert Quarry) and … the neighborhood pizza-delivery boy (Eddie Deezen)!
