O Diabo a Quatro plot
Seventeen-year-old Rita works as a nanny for a rich blond lady with a busy social life. Rita can't take her eyes off Paulo, her surfing neighbor across the street. Paulo is a smoking playboy who either floats on a surfboard in the sea or messes with one of the Copacabana's many prostitutes. And he never has to pay for their services. This much to the dismay of Tim Mais, the tough pimp of the ladies. The shy Rita is fascinated by the world of prostitutes and jealous of the attention they get from Paulo. That is why she reports to Tim as a 'companion lady'. Her stunning body and gentle disposition are a hit with customers, and she soon becomes the star attraction of Tim's business under her working name Mystery. In doing so, she also turns the heads of Tim himself, of Paulo and of the little street boy Waldick. The three men will have to fight for her love.
