After a series of misunderstandings and other unfortunate incidents, the honeymoon of two young couples ends sooner than planned. Back at their starting point, the ensuing conflict leads to one of the couples separating. Salvatore, who moves away, is hit in the street by a car and loses his memory: he has lost his memories of his friends and family - until he meets his wife Marisa, in which he falls in love again ...

Rome, 1957. A woman, Cabiria, is robbed and left to drown by her boyfriend, Giorgio. Rescued, she resumes her life and tries her best to find happiness in a cynical world. Even when she thinks her struggles are over and she has found happiness and contentment, things may not be what they seem.

Romolo and Salvatore look for jobs to impress their girlfriends, but things get complicated when their old flame Giovanna reappears.

Salvatore and Romolo are two young and poor young men that are neighbours and friends. They live with their parents in Piazza Navona, Rome. They are poor but handsome, and both fall in love with Giovanna.
