 Marquinhos is in his early 20s and lives in Copacabana with his petits bourgeois parents and older brother. He doesn t have a job, he doesn t go to school, he just lives on the spur of the moment, watches TV, plays soccer on the beach by day and goes out with his mates by night. He meets Irene, a 40 year-old woman and they have a love affair that is going to change his life - for a while.
