Linda Blair gets mistaken for someone else and she and another woman are thrown into a brutal german prison where she has no rights now. Sylvia Kristel plays the leader of the in for life inmates and she torments others until Blair cannot stand it and fights her. Blair doesn't know that her fiancee and his friends are planning to break her out but they better do it quick before angry Kristel gets to her first. Pretty good with a good score by Tangerine Dream.
