This unusual Italian-Spanish co-production begins with a woman being pulled down into a lake by an unseen assailant. Her daughter Lillian (Eleonora Cristofani under the name "Leonora Fani") returns to her home village years later, and is attacked by an axe-wielding maniac. Lillian has the odd habit of passing out every time she has sex (a very convenient plot twist from screenwriters Leila Buongiomo and Jose Maria Nunez), and one time awakens to find her partners dead. Lillian also has a psychic link with her evil voyeuristic sister Lilith (Patricia Adriani), who is possessed by the spirit of Kira, a long-dead witch, and the two must ultimately duel it out in a climactic catfight in which they rip off each others' clothes. The result is alternately atmospheric and laughably stupid, perhaps explained by director Enzo G. Castellari's last-minute hiring. Castellari is totally out of his element here, and the studio added extra footage after the fact. Nevertheless, there are some interesting moments, and familiar faces like Massimo Vanni, Antonio Mayans, Luis Induni, and American TV veteran Vincent Gardenia for genre devotees. ~ Robert Firsching, Rovi
