 In 1925 the young florentine typographer Mario moves to via del Corno to be near his girl-friend Bianca. Here he becomes friends with Maciste, his landlord, and Ugo, anti-fascists both of them. When Campolmi is beaten by the fascists, Mario meets Milena, Campolmi s wife, at the hospital and falls in love with her leaving Bianca. Then Maciste is killed, again by the fascists, Ugo is wounded and he seeks shelter in ^ÓSignora^Ô s house. Here he falls in love with Gesuina and the two marry. Campolmi dies, but Mario and Milena part themselves. Later Mario too is arrested by the police.
