Four sisters living in an old chteau are convinced that they are vampires. One believes she was raped by the villagers years before, and is blind. Another is afraid of sunlight. They all react violently to crucifixes. The sisters are being manipulated by a sinister old man who alternates between admonishing them to kill newcomers that threaten their exposure, and groping their breasts. The four seem to worship a bestial idol in the forest who speaks to them with a disembodied voice.The newcomers are three Parisians, Thomas Bernard Letrou, Brigitte Solange Pradle and Marc Marquis Polho, who have come to the countryside to cure the sisters of their socalled illness. They do not believe that the sisters are vampires, and dont believe in vampires at all. Thomas is a psychoanalyist, determined to cure them from their madness. He believes it has been induced by the superstitious villagers, who have driven the confused women insane with their religious symbols and persecution. He tries to convince them that crucifixes and sunlight wont harm them, and that the blind sister can actually see. He takes all of this as proof that their vampirism is all in their minds. When one of the sisters fall for Thomas charms, the old man orders another sister to kill him, Brigitte and Marc. When this fails, he unleashes the peasants, who brutally murder all the women they can find, which also includes Brigitte. ........
