While Nobili opens up to Marta, Mazinga expresses his exhaustion with work. Salvatore's long-distance relationship triggers his insecurities.

The unit faces interrogation. Marta fears for her daughter. Nobili earns respect by defending a family during a riot -- while a crisis erupts at home.

Nobili tries to lead the team amid Mazinga's resistance, resulting in another injured agent. Investigations continue as someone questions loyalty.

A demonstration ends violently. Tensions rise with the arrival of the riot squad's new leader and the protest's fallout.
