Werewolf Woman (1976)

Traumatized after a rape at a young age, Daniella (Annik Borrel) hides herself away from the world in her family's estate. In the attic she finds a picture of an ancestor accuse of lycanthropy and burned at the stake. Daniella is the spitting image of her, and eventually begins to believe that she's the reincarnation of her ancestor. Obsessed with the legend, she finds herself tormented by nightmares and frightening visions. After seducing and murdering her sister's husband, Daniella temporarily becomes catatonic and ends up in the psychiatric ward. She isn't there for long, because an encounter with the ward's resident nymphomaniac allows her to escape. The moon seemingly empowers her and sexual acts repulse her. Even seeing others engaged in any type of sexual act is enough to unleash her beastly throat tearing tendencies, and her cross-country path leaves a trail of dead bodies in her wake. In one town Daniella meets a man who isn't only interested in her body, and she begins to fall in love with him. She phones her father to tell him about it, and says she's now cured. Of course the happy times don't last long. A trio of rapists break in and brutalize her. Her boyfriend arrives back home and is murdered. Having her happiness snatched away causes a full mental break, and Daniella hunts them down and kills them in revenge. The police, who have been trying to find her since her escape from the hospital finally track her down.  In a scene reminiscent of the opening scene depicting her ancestor's fate, she is captured. Werewolf Woman, despite the title, is less a werewolf movie and more the story of a woman's descent into madness. With a fair amount of both sleaze and gore, it marks its place as a worthy entry into the Eurotrash genre.
