Innocent, voluptuous Lisa (Elke Sommer) begins her travails when she keeps on encountering a sinister fellow (Telly Savalas), carrying around a mannequin of a man she has killed. Unfortunately for her, she ends up hiding in the mansion of a psycho family where death looms overhead. All of this is intercut with an exorcism story starring Robert Alda as a priest who is trying to help a now-possessed Lisa regain her grip on reality.
