A war between mafia gangs seems to have broken out in Bologna. In the same days Nikita, a girl who works as a pony express, finds 250,000 euros in cash in a package to be delivered. Frightened, the young woman goes to the police station where she meets Inspector Coliandro, who begins to investigate.

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