Luca and his colleagues from the X Tuscolano await Giulia's return from Palermo. But they are not the only ones: on the orders of the lawyer Balsamo, Remo and Diego are ready to blow her up with a car bomb. What Remo does not know is that the lawyer has decided that he too must die in the attack. After the order to abandon the investigation on Balsamo, Giulia decides to continue investigating on her own. She begins to secretly monitor the lawyer's villa, who, however, is already preparing his countermove.
