Marred by controversy at the time of its release, this horror fantasy from Italy's legendary horror director Mario Bava centers on the twisted desires of a nobleman's son (Christopher Lee). Lee is ostracized by his father for his dalliances with a servant girl (who later commits suicide), but is allowed to return to the fold by his brother, whose lovely wife (Dahlia Lavi) immediately becomes the object of Lee's mad lust. Lee is later found murdered, along with several other victims from the surrounding village, leading superstitious locals to believe that Lee's evil spirit has returned to destroy them; the twist ending reveals the real evil at work. The kinky, sadomasochistic relationship between Lee and Lavi raised more than a few censors' eyebrows, leading to some harsh cuts.
