NUNS!… After burning a confessed witch the witchfinders turn their attention to her daughters. Finding the girls in a nunnery where Kathleen is struggling with somewhat impure thoughts they take the girls for questioning in the only way the inquisition knows how. As they struggle to get a confession the zealots begin to fall for the allure of the beautiful Kathleen. Meanwhile Margaret becomes a servant of Satan himself and the sexual intensity the girls suppressed before now becomes their most powerful weapon against those who would see them burn. Jess Franco strikes back with this take on the likes of The Devils and Witchfinder General complete with his sexual slant and a whole lot of unrighteous nuns.
