Rio de Janeiro, 1913. A high-ranking politician is murdered whilst on a visit to an exclusive, sophisticated brothel operating behind the fa§ade of private clinic, and run by a scientist with an obsession for the study of female sexual fantasies. During the investigation, the policeman in charge, himself a regular visitor, is drawn into an erotically charged duel of the mind with the prime suspect. The investigation is a starting point for several stories drawn both from the history and the mythology of Rio.
