In 1925, young Florentine typographer Mario moves to via del Corno to be near his girlfriend Bianca. Here befriends Maciste, his landlord, and Ugo, anti-fascists both of them. After a resident is beaten by the fascists, Mario meets the wife Milena at the hospital, falling in love with her and leaving Bianca. Maciste is killed, again by fascists, while Ugo is wounded and he seeks shelter in a nearby house. Here he falls in love with Gesuina and the two marry. Milena's husband dies, but she and Mario part ways. Later, Mario is arrested by the police.

Guido and Cristina fall in love, but she is betrothed to a solider. When he is reported killed they hope to marry, but his reappearance without his limbs makes matters difficult for all concerned.

Five young men dream of success as they drift lazily through life in a small Italian village. Fausto, the group's leader, is a womanizer; Riccardo craves fame; Alberto is a hopeless dreamer; Moraldo fantasizes about life in the city; and Leopoldo is an aspiring playwright. As Fausto chases a string of women, to the horror of his pregnant wife, the other four blunder their way from one uneventful experience to the next.
