Ettore (Giacomo Piperno) is a charming child at home; on the streets, he is a regular terror. He and his gang of children steal brazenly from the rich, and often engage in rape. After his father is imprisoned for a bungled theft, Ettore quits school and takes a job as a waiter in a bar that specializes in delivering meals to offices and wealthy customers. He has an affair with a rich girl, who shows him another side of life. However, when his father gets out of jail, Ettore masterminds a series of thefts using his experience as a delivery boy in rich neighborhoods. These capers make it possible for his happy family to possess its own bar, managed by the ever-wily Ettore.
