Writer Sílvio Proença needs to travel to São Paulo in order to promote his new book. At the airport, he meets a group of old mates. With the boarding canceled due to a strong storm, the group goes to the apartment of Marialva, daughter of one of Proença's friends. Seduced by Marialva's music and charms, Proença spends the night there, where he wakes up the next day, completely naked. Still groggy from his hangover, he goes to pick up the bread left outside the apartment; that's when the wind closes the door and leaves him naked outside.
