Bare Behind Bars (released in Brazil as A Prisão) is a 1980 sexploitation film directed and written by Oswaldo de Oliveira.,[1] The film, which was intended as a spoof of the common "women in prison" genre, stars Maria Stella Splendore, Marta Anderson and Danielle Ferrite.

[2] The story concerns a group of lesbian inmates who are sexually abused by a sadistic female prison warden.

[1][3][4] In a women's prison in Brazil, the inmates are young and beautiful, the warden is a sadist, all but one of the guards are cruel, and the nurse is incompetent.

To make it difficult for the inmates to hide contraband, they wear no underwear.

They are alternately murderous and orgiastic with each other, and they engage in sex play with some of the guards.
