Diane (
Brinke Stevens), a prim and proper grad student, rents a spooky old house from a creepy realtor (
Michael Berryman). Unfortunately for Diane, an ancient
demon (Oliver Darrow) resides in her basement. Diane is soon
possessed by the spirits of the house, who turn her into a leather-clad, chainsaw-wielding
succubus. When Diane's sister Sally (Elena Sahagun), Sally's brother-in-law Mike (Jay Richardson) and Diane's boyfriend Jeff (Tom Shell) come to visit only to be attacked by Diane's demonic incarnation, they summon a priest, Father McFerrin (
Robert Quarry), to handle the situation. Failing in the task, Father McFerrin attempts to call an
exorcist, only to dial the wrong number and unwittingly place an order at the local pizza parlor. When the
pizza delivery boy (
Eddie Deezen) arrives at the house, it's up to him and the rest of the gang to destroy the demon and stop his nefarious scheme. ==Cast==
