7x10 - Distretto di Polizia

A criminal gunsmith is found brutally murdered in the back room of his front shop. The agents of the 10th Tuscolano investigate and a neighbor recognizes Petrocchi from the signs, an elderly thief expert in safes, now on semi-liberty. The man denies being in the business but a nasty surprise awaits him. In the meantime, the statements of Nina, who has decided to collaborate without further reticence, cause many arrests in the clan and the escape of a fixer who asks for Fontana's protection.
