A war between mafia clans appears to have broken out in Bologna. Around the same time, Nikita, a young woman working as a delivery driver, finds €250,000 in cash in a package. Frightened, the young woman goes to the police station where she meets Inspector Coliandro, who begins investigating.

While Trombetti was taking his niece Angelica home, accompanied by Coliandro, his car was rammed by a scooter driven by a Chinese boy who immediately disappeared into thin air.

A suspect dies during a police operation in the tough Pilastro neighborhood, apparently killed by a gunshot fired from Inspector Trombetti's weapon. Coliandro investigates to try to exonerate his colleague.

A young black girl is killed during what appears to be a voodoo ritual. Coliandro is assigned to care for the victim's sister, who has arrived in Bologna from Africa.

During a nighttime chase through the streets of Bologna, a young woman steals Coliandro's gun. While trying to track down the unknown woman, the inspector stumbles upon a dangerous criminal organization.

On the estate of a very wealthy man, an escort is cruelly murdered by a cold and determined hitman. The investigation leads Coliandro into the world of high-class prostitution.

Coliandro is caught up in a bank robbery in downtown Bologna. The three young and inexperienced robbers are quickly subdued by three hostages, who, in turn, take the others hostage.

Two gypsy girls steal something very important from the home of the wrong person, a corrupt Carabinieri marshal, who attempts to take revenge by ambushing them. One of the girls seeks refuge in Coliandro's house, seeking help.

In the trial against the Casalesi clan boss, the Bologna prosecutor's office must rely on the testimony of Jelena, who is now under protection. Coliandro, still in love with the woman, learns of her new cover and decides to visit her. There, however, he must contend with two seasoned killers.

As punishment, Coliandro has been transferred again, this time to the tedious canine unit. His sister comes to visit him, deeply concerned about her daughter Angelica, who is dating a boy associated with a satanic cult.
