Ardenzi and Belli are trying to track down a robber, while Ingargiola, Vittoria Guerra and Parmesan receive a series of strange reports from men who claim to have been robbed under a specific overpass, all in different circumstances. Meanwhile, Giulia receives important revelations about her father's murder.

This time Mauro and Roberto are engaged in a desperate chase: a woman has kidnapped her eight-year-old daughter from school and, in a state of delirium, has involved her in a crazy car race to reach her husband's lover, whom she holds responsible for the failure of her marriage. Meanwhile, Parmesan discovers that his credit card has been cloned and that a lot of money has disappeared from his account.

Unexpected news reaches the Decimo Tuscolano. In fact, while Roberto, happy about some sentimental news, receives the official transfer letter, Mauro discovers that a friend of his, an aspiring boxer, is in a coma in the hospital after being violently beaten. The agents understand that the victim is involved in a clandestine betting ring and Paolo, who has years of kickboxing training behind him, offers to go, as an infiltrator, to the gym frequented by the beaten boy.

Meanwhile, the agents of the X° Tuscolano try to foil the attempted kidnapping of a child, based on some photos found in the basement where Ira worked.

Meanwhile, Luca and Corrado deal with the case of a woman who disappeared after a car accident.

Giulia and Mauro call the forensic team to remove the microphones hidden inside the police station. Someone who has free access to the rooms of the X° Tuscolano has managed to place them undisturbed, perhaps one of the most unsuspected people. The solution to all the mysteries is about to be revealed once and for all.
