A total re-edit of Mario Bava's gothic classic Lisa and the Devil (1973) for US release in 1975. Cheesy exorcism scenes were shot to try to capitalize on the success of The Exorcist (1973).

Lisa is a tourist in an ancient city. When she gets lost, she finds an old mansion in which to shelter. Soon she is sucked into a vortex of deception, debauchery and evil presided over by housekeeper Leandre.
