Several struggling bohemians try to survive in the Latin Quarter of Paris in the winter of 1830, hoping to one day become famous. Playwright Rodolphe (John Gilbert) and his painter roommate Marcel (Gino Corrado) have trouble with Bernard (Eugene Pouyet), the landlord, who threatens to throw them out if they do not come up with the monthly rent that night.

The film is a romantic melodrama about two childhood friends who grow up to be soldiers in Germany. One of the friends, Leo (Gilbert), becomes infatuated with Felicitas (Garbo), the wife of a powerful count (a marriage about which Felicitas neglects to inform Leo). The count calls for a duel of honor with Leo, but insists that it be done under the false pretense that the quarrel was due to angry words exchanged between the two at a card game in order to protect the count's reputation. Leo kills the count in the duel, but then is punished by the military, being sent away to Africa for five years.
Ahmed, the adult son of Sheik Ahmed (Valentino played both roles) is just as impetuous as his father once was. At the beginning of the movie, he is wooing the dancing girl Yasmin (Banky), who is exploited and overworked by her renegade French father. During one of their trysts at a moonlit ruins, Ahmed is kidnapped and later tortured by Yasmin's father and his cronies, who hope to receive a large ransom from Ahmed's father. Ahmed is rescued by his loyal servant Ramadan. Having been misled into believing that Yasmin was the one who set up his capture, Ahmed kidnaps her in turn and imprisons her in his tent. It is heavily implied that she is then raped, but the scene fades out before anything of consequence happens, and the exact details are left to the viewers' imagination. Ahmed's father, angered at his son's long absence from home, arrives and insists that he free Yasmin. When a remorseful Ahmed learns that Yasmin actually wasn't involved in his kidnapping, he sets off to free her from her father (who is trying to force her to marry one of his henchmen). All is forgiven, and the movie ends with Yasmin and Ahmed reunited, presumably to wed and live happily ever after.
