Investigating magistrate Nino Scotellaro is on the trail of Mariano Suro. He has been hunting the fugitive boss of Cosa Nostra for years. This time he really is just one step away from catching him. But when the arrest fails, a furious Nino points his finger at the institutions, which he believes are accomplices. This accusation, however, will backfire, eventually taking everything away from him.

Now that Nino is "free" again, it is hard for him not to think about his previous life. But the desire to avenge all he has lost takes over. And so, in his new identity as a Mafioso, he becomes part of another "family": the Tracinas, a clan in decline, rivals to Suro. Together with them, he begins his revenge. To fight Suro, though, they need weapons.
