Giulio discovers that years before his father, to indulge his passion for engines, had left him a mechanical workshop, which was then sold, without his knowledge, by Cesare to pay off the debts of the liquor store. The Cesaroni family and the customers of the wine shop are in a frenzy: soon there will be a derby between the football team of the Garbatella neighborhood and the team of the neighboring neighborhood. Captain Giulio, overcoming Lucia's resistance, decides to participate.
