A young magistrate makes the decision to denounce his boss after suspecting him of collusion with the underworld. Meanwhile, the Corleone mafia feels the increasing threat of former members.

Saverio is entrusted with a new task: to travel to Switzerland in order to recover millions of dollars.

Saverio manages to obtain the investigation of his first fugitive, Mico Farinella, but in eight months the research does not produce any results. Meanwhile, Tony Calvaruso is involved in the sale of some apartments.

Bagarella has triggered a real war among the Corleone and the Villabate, and the list of victims continues to grow. Saverio Barone is helped by the lover of a mafia boss during the investigation.

After they get a confession from Salvatore Barbagallo, Barone and Mazza are in a position to dismember the Di Peri clan and try their best to put an end to the bloody clan war.

Mazza begins a new line of investigation, dedicated solely to the godfather Pasquale De Filippo. Plus, Bagarella suspends the war between clans, and Saverio finds a figure of his own past.

The police manage to find the den of Pasquale De Filippo when following the footsteps of Lucio Raja. Meanwhile, after being prompted by Don Luchino, Bagarella returns to full activity.

Mazza and Saverio are hot on the trail of Bagarella to identify Tony Cavaluso and learn what they need to do in order to take down the boss. An irruption could stop the dangerous criminal.

Thanks to the irruption orchestrated by Saverio and Mazza, Leoluca Bagarella is finally arrested, and some of his trustees are also placed in handcuffs. Plus, Giovanni Brusca becomes the head of Cosa Nostra.

Saverio, now with Bagarella finally arrested, is more calm and closer to getting married. Now, the most wanted man from the Antimafia is Giuseppe Di Matteo and the Mafia prepare an explosive plan.

The wedding day of Saverio is looming closer and the man receives a dangerous invitation. Plus, Brusca has now completely taken over the domain of illicit trafficking and the Dome.
