We Were Children.

In a police station in a small village, a sergeant interrogates a young and frightened postman, known as "Cacasotto". He, normally known for being calm and good-hearted, was arrested for having threatened a policeman on patrol with a knife. Eventually, Cacasotto begins to speak with the cop. And he tells what happened twenty years earlier to him and to his five best friends: Gianluca, Walter, Peppino, Margherita and his little brother, Andrea.
