After the robbery at Mauro and Germana's house, the couple moves to Roberto's house, significantly reducing his privacy with Francesca. But there's no time for personal complaints: the agents have to deal with a girl injured by an anonymous man who shot her from afar. It could be a sniper. Meanwhile, Ugo and Vittoria solve the case of a teacher who is the victim of obscene anonymous phone calls. Meanwhile, something happens between Ingargiola and Vittoria that they would never have expected. Mauro and Roberto run to stop a man who is blatantly about to shoot himself in the street. Giulia, in the meantime, continues to investigate Paolo's death, based on some photos examined by the forensic team.
