Due piedi sinistri

A 10-year-old boy is in the car with his Roman and Romanist father. They are late because the derby is about to start, but first they have to go to a place. The child is dressed in a fluttering blue miniskirt and a cape like a superheroine. They arrive at the supposed show. Ettore begins to sing a song with female movements, but after a few bars, he is interrupted. He is not in school, but in a room of a pediatric hospital and in front of him there is a friend of his who is taken to the operating room.

A police inspector has to help an eccentric stranger who seems to have lost his memory.
