Inspired by the masterpiece of concrete music "Symphony for one man" Pierre Henry (1950), the film tells the story of a common man leaving the interior of Brazil to try life in São Paulo. The city, in its perpetual process of construction and deconstruction view from the microcosm of a construction site, its workers and a profusion of machines in full swing. The metaphysical revolt of this character is the revolt against his condition and against everything that humiliates him.

A down-on-her-luck former inmate tries to reconnect with her daughter--to the objections of her sister who raised the girl, meets a millionaire, and transforms into a strong woman, returning to society at Dancin' Days nightclub's opening.

When his father passes away, Estácio and his aunt Úrsula receive his will and are surprised to discover that most of the inheritance was left to Helena, a previously unknown daughter. In the will, her father asks that his daughter be taken in by her relatives. The news infuriates Úrsula, who has been in charge of the family business and caring for Estácio since his mother passed away, and does not accept Helena willingly, seeing her as an intruder in the family. In addition to Úrsula, someone who is not pleased with the girl's arrival is Dr. Camargo (Rogério Fróes), father of Eugênia, Estácio's fiancée. Even so, Estácio obeys his father's request and takes the girl to live with his family. Helena has a cheerful and outgoing temperament and her arrival affects everyone's lives. At first, she is hostile to Úrsula, but later wins her sympathy.
