November 2, 1975: Pier Paolo Pasolini is murdered in the outskirts of Rome. The suspect, a 17-year-old hustler, pleads to have acted in self-defense, citing Pasolini's notorious sexual habits as proof. However, many inconsistencies start to undermine his version, pointing to him not having acted alone or even being assaulted in the first place. Was Pasolini also killed for another reason?

The "Brigatte Veneno" is a fan group from the soccer club "AS Roma". The next match is against "Juventus Turin", the classic prestige duel. Principe, the former leader of the group, has been dismissed from jail a few days before. He has to realize that his best friend Red has not only taken over control of the group, but also has started an affair with his girlfriend. The rivalry between the hot-blooded Principe and the sensible Red causes an anxious mood within the group. When Smilzo, a member of the group, dies during a street fight with another fan group, Red knows that Principe is to be blamed for this catastrophe.
