A young Colombian, stopped by the police at the Venice airport, is found in possession of cocaine and confesses that he had to deliver it to the 'Zodiaco' pension. The policemen go to the appointment and, when Nazzareno Corradi knocks on the door of the room, they arrest him accusing him of international drug trafficking. The lawyer Bonotto, who defends Corradi, contacts the Alligator. He believes his client is the victim of a plot, a police revenge for a robbery that took place years earlier in which two officers died. The Alligator once again decides to take the case.
