A young girl enters a convent during the Inquisition, and discovers that the nuns and head priest are a coven of Satan worshipers. Not sure how I should feel about a flick where a teenager (the actress looks really young) gets stripped nude and raped by Lucifer himself. Lots of fun medieval torture, including the rack, nipple clamps, crucifixions, etc. Franco had a budget for this one, and it shows in the lavish costuming and great photography.
