Women in Cellblock 9 (German: Frauen für Zellenblock 9) is a 1977 Swiss exploitation action film written and directed by Jess Franco and starring Karine Gambier.

The three detainees, Karine, Barbara, and Aida, are found shortly thereafter, naked and chained in a standing position, in the notorious Cellblock 9.

Karine and Marie go into the jungle to look for food, but the guards find their trail and meet them at the temple.

As Barbara is killed, the other two, alerted by her screams, run back to the temple and are suddenly confronted by the camp commander and the doctor (surrounded by prison guards).

In the United Kingdom, the film was refused classification by the British Board of Film Classification (BBFC) in February 2004, with the board citing potential legal issues under the Video Recordings Act 1984, as well as pending updates made to the Protection of Children Act 1978 in England and Wales (under the Sexual Offences Act 2003) set to take effect in May 2004, as issues prohibiting the classification of the film.

We find pretty, young women who are forced to be nude most of the film and are degraded physically, mentally, and sexually.
