Sad story of a waif, Gelsomina, who is sold by her mother to Zampano for 10,000 lire and a few kilos of food. Zampano is a traveling showman who exhibits feats of strength by breaking a chain wrapped around his chest. He performs in village squares and then passes the hat for whatever the normally small crowd is prepared to give. He teaches Gelsomina a drum roll as part of his introduction. He doesn't treat her well and when she tries to run away, he beats her. They eventually join a small traveling circus where they meet Il Matto but a disagreement leads to tragedy. Zampano eventually abandons the girl and it's only many years later that he learns of her fate.

Cabiria is a wide-eyed waif, a streetwalker living in a poor section of Rome where she owns her little house, has a bank account, and dreams of a miracle. We follow her nights (and days): a boyfriend steals 40,000 lire from her and nearly drowns her, a movie star on the Via Veneto takes her home with him, at a local shrine she seeks the Madonna's intercession, then she meets an accountant who's seen her, hypnotized on a vaudeville stage, acting out her heart's longings. He courts her. Is it fate that led to their meeting? Is this finally a man who appreciates her for who she is?
