[1][2][3] Paolo Torregiani is a night watchman who has been working in Lucca for twenty years in a security agency.

After a violent argument with his colleague Alcide, he tries to make peace but he finds him in a puddle of blood, hit by a bullet in the abdomen, inside a shoe factory where he was guarding.

Since Daria left him, Paolo began to invade Nadia and spend part of the night next to her windows.

That night, by chance, Paul can talk to her, as she accompanies her to search for the husband who is not aware of the incident.

From that moment on, Paolo starts to split between the episode about his colleague and this 'assignment' that allows him to stay close to the woman he wants.
