After intercepting a call, police officer Carlo conducts a drug bust at a private party at the upper-class apartment of Rosanna Clerici and she is arrested. Just as the police and party guests are leaving, Rosanna's 6-year-old son Giulio comes out of his room and asks Carlo where his mother is. Since Carlo is responsible for his mother's arrest, Giulio tags along with him until she is freed. Carlo tries to get Social Services to look after him, but the Courts tell him that he's the best choice for caregiver until a better one is found. Although Giulio disarranges Carlo's life, Carlo gets to like Giulio and falls for Rosanna while she's in prison. It ends with Rosanna being released from prison and the three of them going out to dinner.
