This film captures the criminal behavior of two young Copacabana thugs (the "cafajestes"). The two plan a blackmail coup against a rich old man, using nude pictures of a lady on a deserted beach. But things don't always happen as planned.

Jandir and Vavá are two scums and small time crooks from Copacabana, who want to raise some easy money shooting compromising pictures of Leda and blackmailing her rich uncle. Leda convinces them to use her cousin Vilma, the daughter of the victim.—Claudio Carvalho, Rio de Janeiro, Brazil
