Frauengefängnis
Frauengefängnis (released in the US as Barbed Wire Dolls and in the UK as Caged Women) is a 1975 Swiss horror film directed by Jesus Franco. It is part of the women in prison cycle of violent sexploitation films that flourished in the 1970s and early 1980s.
When originally submitted for release in 1976, the British Board of Film Classification rejected it. It was only passed the following year after extensive cuts.
