The film is inspired by the events of violence that occurred in Piazza San Babila in Milan in 1975, where groups of neo-fascists and anarchist communists were the protagonists. Four Milanese boys are part of a fascist group, claiming with all sorts of violence a new order based on the squadrism of Benito Mussolini. The boys are fighting with the institutions and against the youth group of the communists and the anarchists, and often collide during the protests, with violent outcomes.
