Die Marquise von Sade

Lady Doriana Grey, who haunts her isolated castle, and her twin sister who has been driven insane after being institutionalised at a young age. In the mental facility, the sister is under the care of Dr. Orloff. The two share a psychic connection, and along with their similar looks, they apparently have another common bond. It would seem that Doriana is unable to experience sexual satisfaction. Her enigmatic presence brings her many lovers; mostly female who are unable to resist her charms.
