Professor Silvio Proenca is a specialist in traditional Brazilian music, and lives in
Rio with his wife. While on a trip to Sao Paolo where he must attend a conference, Silvio
meets a friend and his pretty manager Marialva, at the airport. When the flight is delayed
he ends up spending the night with the young woman. In the morning, Silvio steps out to
collect a bag, when suddenly he finds the door locked behind him. When neighbors emerge
to find him completely naked, he must escape the area with only the barest of essentials.
