Plot: The first Franco/Erwin Dietrich effort is probably Franco's most exploitive film with numerous sadistic scenes of torture and perversion. A true exploitation masterpiece that only a director like Franco could make. Maria (Lina Romay) is sentenced to prison for life for killing her father that attempted to rape. She is sent to a special section of the jail know for it's cruel and sadistic treatment of prisoners. The wardress (Monica Swinn) is a sadistic lesbian who knows no mercy and takes pleasure in her job. Maria seduces a male nurse who she eventually kills in order to spring an escape from the hellhole. A must for all fans of sadistic WIP films and for Jess Franco addicts. Also stars Franco regulars Paul Muller, Martine Stedilm and Eric Falk.
