Remember the Marquis De Sade who boldly challenged the boundaries of lust and morality in quill pens? Although the film does not feature him as the protagonist, it has a lot to do with the contemporary avant-garde whose name has been extended to "SM". Dr. Maitland, a collector with a penchant for collecting items related to dark magic, recently acquired a skeleton claimed to be the Marquis of Sade, and the doctor soon discovered that he had been influenced by the mysterious power of the skeleton and turned into a crazy monster. This film is based on a short story by Rob Bloch and is a classic horror business card directed by Freddy Francis in 1965.
