While Giulia is in the hospital, the activities of the Decimo Tuscolano do not stop. Ingargiola, Vittoria and Parmesan investigate the case of a girl who ended up in a coma due to a drug used to lose weight; Luca and Roberto deal with a boy who passes himself off as a policeman by giving punishments to small-time criminals; Paolo and Mauro, instead, try to understand the causes of Giulia's accident. Giulia returns to the police station more combative than ever, determined to frame Greco, with the help of Mauro and Paolo. In the meantime, however, she must solve a new case: a young man is found dead in his pizzeria. The sister of the murdered man accuses her father, but the real culprit will soon come out into the open.
