During the security service at the city stadium, Coliandro and agent Balboni arrest an ultra who had tried to stab a policeman: terrified of ending up in prison, the boy collaborates and provides the policemen with some important information.

In the trial against the boss of the Casalesi clan, the Bologna prosecutor's office has to rely on the testimony of Jelena, who now lives under protection. Coliandro, still in love with the woman, learns of her new cover and decides to go and see her. But there he has to contend with two fierce killers.
