In a war-torn corner of the dangerous South American jungles, a small group of suspected female dissidents falls into the hands of the military police. Left to rot in the infamous cell block 9, the helpless shackled prisoners must endure humiliation, torture, and sexual assault, as the camp's sadistic physician, Dr Milton Costa, tries every trick in the book to squeeze information out of them and learn the location of their secret organisation. But time is against the captured female inmates. Has anyone ever escaped from the hellish women's prison and lived to tell the tale?
