Directed by Juan López Moctezuma • 1977 • Mexico
Starring Tina Romero, Susana Kamini, Claudio Brook

Directed at fever-pitch hysteria by Alejandro Jodorowsky collaborator Juan López Moctezuma, this ultrablasphemous satanic shocker is one of the unholy grails of the nunsploitation genre—an orgiastic freakout of Catholic imagery, vampirism, lesbianism, and demonic possession. Following the death of her parents, teenage Justine (Susana Kamini) arrives at a convent where she strikes up a curious friendship with the mysterious Alucarda (Tina Romero)—a relationship that will unleash a most ungodly terror within their cloistered world.
