At X Tuscolano, the arrival of a new agent, Corrado, presumed son of Ingargiola, is celebrated. Luca immediately involves him in reporting a robbery at a gas station by two motorcyclists, unrecognizable because of their helmets. The young man's debut in the police force will not be very simple. Giulia, meanwhile, very worried about the disappearance of Paolo who did not return home during the night, alerts Roberto and Mauro to explore every single lead in the area. The clues that the agents find to trace Paolo are not, however, very comforting. While the desperate search for Paolo continues, a new case involves Luca and Corrado: the discovery of the body of a young Albanian woman, which will lead them to investigate a prostitution ring. Vittoria and Ingargiola, on the other hand, are busy solving a blackmail issue.
