Synopsis by Sandra Brennan
After being dissatisfied with Mario Bava's original cut of Lisa and the Devil, producer Alfredo Leone decided to capitalize on the continued popularity of The Exorcist and inserted a handful of exorcism scenes (shot with the assistance of Bava) into the film and releasing it under the title, House of Exorcism. 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.
