Police District

In this eleventh and final season, Vittoria Guerra and Giuseppe Ingargiola are leaving the scene. The new commissioner will be Leonardo Brandi, an old friend of Luca's.

In season ten, the Tuscolano 10th unit is at risk of closure due to staff shortages, and the few remaining units are disheartened. Luca has become deputy commissioner, while Giulia Corsi decides to return to Rome to investigate a group of drug dealers linked to the Palermo underworld, against the wishes of her superiors.

Luca Benvenuto is appointed chief commissioner of the 10th Tuscolano precinct, while Raffaele Marchetti also leaves the series after the first four episodes. Alessandro Berti also leaves the precinct, having left for America at the end of the previous series.

In season eight, after the departure of Commissioner Marcello Fontana, who preferred to return to Calabria with his wife and son, Luca Benvenuto takes over the police station. The team is also joined by Inspector Elena Argenti and her brother Marco.

In the seventh season, Roberto Ardenzi leaves the precinct to join the anti-mafia unit, and Commissioner Marcello Fontana takes his place. Inspector Raffaele Marchetti also joins the team. In this series, Commissioner Fontana must deal with an investigation involving the 'Ndrangheta.

The sixth season begins with a change in the precinct leadership: Giulia Corsi moves to Trieste to follow Carabinieri Captain Rea, and her place is taken by Roberto Ardenzi, who is also in his final year at the precinct. Inspector Irene Valli and Inspector Alessandro Berti join the team.

In this fifth season, a new elite officer, Anna Gori, arrives at Precinct X Tuscolano, where she will team up with Luca Benvenuto. Meanwhile, a Carabinieri captain, Davide Rea, played by Giampaolo Morelli, tries to gain the trust of Commissioner Corsi and investigates the shooting that left Inspector Belli's wife, Germana Mori, injured and in a coma.

In this gripping fourth season, Commissioner Giulia Corsi will have to deal with her father's murderers, who will do everything they can to stop the agents of the Tuscolano Tenth in their investigation, hitting the Commissioner where she is most dear.
