Marco, thanks to the trust that Aurelio shows him, accepts the invitation of his policeman friend and becomes the first civilian infiltrator in history. The thousand lies and the many displacements he is forced to do create a growing tension with his wife, his father and his family. Furthermore, Aurelio's attitude, who treats him almost like a brother, makes Inspector Vexina suspicious.

Marco, forced by Aurelio to leave for South America, meets the boss's family and his fellow traffickers. The man would like to end that story, but Mario convinces him to accept one last job: preparing a boat for a special delivery. Aurelio, at the last moment, asks that Marco be the one to drive the boat. Marco hesitates but the Italian police guarantee him protection.

Marco is sentenced to eight months in prison. While sharing his cell with Pablo he tries to get in touch with the Italian police to no avail. When he realizes that if he is found to be an infiltrator he and his family would be finished, he silently accepts the sentence.
