Black Magic Rites features satanic rituals in an ancient castle's underground vaults which revive a witch who was killed over 400 years ago. The rites involve slaughtering seven naked virgins, already dazed by their experiences during a demonic orgy. The ritual is interrupted by one of the women's lovers who tries to save her. There follows a series of frenzied and crazed depictions of torture, burnings, and SM sex Italian-style, in what has to be one of the most bizarre horror films ever made.
