1993. Saverio Barone, a young magistrate serving in Termini Imerese near Palermo, decides in a mix of ambition and sense of duty to denounce his boss, Salvatore Donà, to the CSM, suspecting his collusion with the local mafia.
Saverio has been part of the Anti-Mafia Pool for a few months. His colleagues treat him with disregard and have not yet been able to show their value. Finally an opportunity arises.
After taking over his first investigation of a fugitive of the law, Mico Farinella, Saverio has not been able to produce any results in eight months. One day, however, the unthinkable happens.
Saverio, with the support of Captain Bonanno's Carabinieri, manages to get back on the trail of Mico Farinella. Finally, after months of waiting, the investigation has tightened the noose around the neck of the Madonie boss.
Bagarella has started a war. A trail of bodies lies between Corleone and Villabate, which forms a unit out of the investigating team Mazza/Barone, but it also leads to Saverio spending more and more time away from home trying to understand what is happening.
Barbagallo turns out to be the key to the investigation. Thanks to his confession, Saverio and Mazza can try to dismember the Di Peri clan and, even without approaching Bagarella, put an end to that bloody war.
Bagarella, in mourning, decides to suspend the war. Tony has the opportunity to dedicate himself to a new business venture: a jeans store to be managed together with Tullio Cannella.
The investigation on Raja has unveiled Di Filippo's hideout. They stake out the place and plant listening devices, waiting for something that could take them to Bagarella.
Five months have passed and Saverio has changed: balanced, serene, and he is getting married. At the center of the investigation are the last of Bagarella's men who are still at large.
Bagarella's evasion plan is off and Brusca can cheer: now he has a castle, an arsenal, a drug trafficking operation all of his own and Don Luchino is out of the way.
