Season 7

Several characters return to the little town where, years ago, the police commissary Cattani was set up and murdered by the Mafia.

Sara and Biagio, her brother, create an extortion gang, named after the village's suburbs where they live. They are taking the "business" out of Nuzzio's hands.

Saverio comes home to reunite with Nuzzio against the higher powers of the Mafia, but these are alert and after him, after torturing his mistress in St. Petersburg. Also after him, is his wife, still under the protection of Oleg, Saverio's bodyguard.

The local television channel, owned by Olga Camastra, puts the blame of her husband's death on Silvia Conti's harsh interrogation of the old man. Saverio's ascension to power seems unstoppable: he masters over Nuzzio with his superior intelligence, and helps him escape an ambush; the Barrotti gang is massacred by Nuzzio's men; and he breaks and enters into the countess's palace, frightening her, and demanding the names list.

Silvia is blamed for another strange death, the young commissary Breda is sent away to his hometown far north - something he had requested before he was into this case - and their only witness, Sara, is pressed by a police inspector and the new prosecutor to deny her earlier testimony.

The killing attempt worked almost to perfection, and more blood runs in the streets. Silvia Conti's life is spared due to the intervention of Oleg, Saverio's bodyguard, who decided against Nuzzio's opinion that she would be more valuable to them alive.
