Journey to the Roof of the Mouth[1981]

Nilo Barrão steals a car from the telephone company and robs the mansion of Mara, the wife of an industrialist on vacation. A nymphomaniac, she demands that Nilo rapes her, but he only partially satisfies her wishes, as he prefers to plan physical violence against Paula, a transvestite who lives in the same house, with Mara's help. The arrival of a nearsighted enumerator interrupts, for a moment, the sadomasochistic game. Teresinha, Mara's adoptive niece, upon returning from school, is de-virginized, with her consent, by Nilo. Paula, suddenly transformed into a sorceress, decides to take revenge.
