Summer Sunday at a small beach house at the coast of Rome. Many people and stories: women's basketball team, two sports-obsessed soldiers, two men with their girlfriends and the priest with a big secret, an elderly couple with their pregnant granddaughter, and engagemented couple wanting to have sex for the first time.
In Pietrasanta all are excited for the annual party of summer end. Here we find four characters: Merigo, a naive guy passionate of bike; Pierre, son of the mayor; Simone, a pestiferous kid; Mario, lifeguard of "Bagnomaria".
Broke, and armed only with his sense of humor, middle-aged Gianni lives with his mother in their old apartment. The debts are mounting, but if Gianni looks after the building manager's mother during the Ferragosto, a mid-August holiday, all will be forgiven.
