A disturbed woman slips over the edge into violent madness in this low-budget horror story. Grace (Brooke Mills) was abandoned by her parents as an infant, and grew up in an orphanage. As an adult, Grace is engaged to Patrick (Paul Prokop), a medical student, and she performs as a high-dive artist in a bizarre Christian revival show staged by Patrick's brother Jesse (Michael Pataki); Grace shares enough of Jesse's religious convictions to insist on abstaining from sex before marriage, though she struggles with her physical desires. The scars from Grace's unpleasant childhood cause her to drift in and out of a world of her own, and she wants to find closure by locating her long-lost father. While looking for her dad, Grace finds her way to a cheap hotel, where a pimp (Marc Lawrence) informs her that he knew her father, and that he died the night before. When Grace sees the dead body of her father (Edmond O'Brien) in the morgue, she snaps and imagines that the corpse has come to life. As Grace drifts deeper into her fantasy world, she goes on a spree of violence and lust fueled by the demons in her mind and the actions of her re-animated dad.
