While visiting Toledo, Spain, American tourist Lisa Reiner (Elke Sommer) experiences a feeling of deja vu when she sees an ancient mural of the Devil carrying away the dead. Hearing a familiar melody, she wanders away ...展开from her companions into a series of encounters with men who inexplicably recognize her from a past life. Hopelessly lost as night falls, Lisa begs a ride from a passing Packard, which breaks down outside a mansion where a young man (Alessio Orano) lives with his blind mother (Alida Valli) and a charming butler (Telly Savalas), who just happens to resemble the Devil from the mural! After a night of murder, necrophilia and horrific revelations, Lisa comes face-to-face with the secrets of her past identity and her connection to the bizarre rituals she has witnessed. This is the original Mario Bava film later reworked and reshot for American release as "The House of Exorcism."
