In return he has to make a detainee, magistrate Vittorio Mancuso, accused of the murder of an employee of Slimpetroil Spa, a renowned national energy company, talk, finding out why he was guilty of that crime before the man testifies before a judge. When Bruno begins to suspect his innocence and fear that the services are using him, he decides to get to the bottom of it. It will be the beginning of a battle for the truth and the price to pay will prove to be very high. (Source: Translated from official synopsis via DeepL)
