Plot
Maria da Guerra kills her father, who was trying to rape her. She is imprisoned in a jail where lesbian wardens torture the inmates.
The women's prison, set on an isolated island, is run by a man who impersonates a doctor, Carlos Costa. In fact, he is a killer who murdered the actual doctor of that name, whose name he then assumed. Assisting him is a monocled lesbian woman known only as The Wardress who regulates the prison with an iron fist. The Wardress reads Nazi volumes such as Albert Speer's history of the Third Reich as leisure reading. She wears jackboots and tight shorts under a white shirt in some scenes. In other scenes she wears a see-through black sheer fabric top.
Due to the practice of placing prisoners in isolation and torturing them (for example, via chaining them naked to a wall just out of reach of food, or placing them naked on a wire-frame bed where they receive electric shocks), several prisoners in the past have died. The current authorities in charge of the prison have concealed this by claiming these prisoners died of heart failure; but they are reaching the point where any more reported 'heart failures' will appear suspicious to the authorities on the mainland.
