Accio and Manrico are two working-class brothers in 1960s Italy: older Manrico is handsome, charismatic, womanizing, and loved by all, while younger Accio is moody, hotheaded, and lives everything as if it was a war, much to his parents' chagrin. While the former is drawn into left-wing politics, Accio joins the fascists out of spite. His flimsy beliefs are put to test when he falls in love with Manrico's like-minded girlfriend.
