Sezon 1

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.
