An incident sparks internal conflict as members of a riot squad juggle personal worries with the daily tension of police work on the streets.

A night of ferocious clashes in Val di Susa. A team of the Mobile Department of Rome loses its leader, who is seriously injured. That of Mazinga, Marta and Salvatore, however, is not a team like the others, it is Rome, which has learned to oppose the disorders with extreme methods and a tribal harmony, almost from family. A family that the new commander, Michele, son of the reformist police, will have to deal with, for whom teams like that are the symbol of an old school, yet to be re-founded. As if the chaos that affects the new formation at the moment of maximum internal fragility was not enough, there is also that given by a new wave of people's discontent towards the institutions. A new "hot autumn" against which our own people are called to take sides and in which each protagonist is forced to question the deepest meaning of their work and their belonging to the team.
