A new female inmate at an island prison is abused by fellow convicts and staff, and her disillusionment with the new warden prompts her to join in an attempted breakout and mutiny.

New inmate Marie arrives at an island prison in the women's sector and receives the number 99. The inmates are controlled by the sadistic lesbian warden Thelma Diaz and Governor Santos and submitted to torture, rape, sexual harassment and abuse. When the Justice minister replaces Diaz, Marie believes that her life will improve and her case will be reopened. Marie's disappointed with the new warden and plans to escape. But their scheme fails and the abuse they've undergone had been but a paltry hint of the torture in store.—Claudio Carvalho, Rio de Janeiro, Brazil
