Giovanni Rocca is a cunning Carabinieri marshal who works at a barracks in Viterbo. A widower for many years, he has three children: Giacomo, Daniela, and Roberto. His investigations often involve his family, but thanks to his intuition, the marshal always sniffs out the right leads, managing to protect his loved ones and bring criminals to justice. The episode that will profoundly impact the first season is the untimely death of Carabiniere Antonio Fait, one of Rocca's best men, killed by a gang of drug traffickers. However, love is not lacking: the marshal begins a relationship with the pharmacist Margherita, dividing his time between her, his family, and his work.
