Gianni certainly expected the holidays around the "Ferragosto" in the middle of August to be different! In the summer heat, the eternal bachelor suddenly becomes the host of four headstrong old ladies. Nevertheless, Gianni, who as a typical "mammone" still lives with his mother, takes up his challenge. His patience and good-naturedness are put to the test for 24 hours. But when the moment of farewell arrives and Gianni believes he is free of his imposed host duties, the group forges other plans.
