Overview: This time Mauro and Roberto are engaged in a desperate chase: a woman has kidnapped her eight-year-old daughter from school and, in a state of delirium, has involved her in a crazy car race to reach her husband's lover, whom she holds responsible for the failure of her marriage. Meanwhile, Parmesan discovers that his credit card has been cloned and that a lot of money has disappeared from his account. His colleagues from the X° Tuscolano immediately try to help him discover the person responsible for the scam. Giulia and Paolo, in the meantime, receive a mysterious envelope addressed to Commissioner Corsi.
