This season, the Marshal is dealing with Giacomo, who is unsure about his choice of marriage, and with Tommy's biological father, who extorts money from Margherita in exchange for the child. Margherita is also jealous of Rocca's closeness to Dr. Ascari, the new deputy prosecutor, and to appease her, the Marshal promises her the honeymoon they never had. On the morning of their departure, however, a boss enemy of Rocca plants a bomb in his car, which Margherita has just gotten into, and the car blows up before the Marshal's eyes. The boss is later captured by Rocca.
