In the tenement slums of Paris between the world wars, impoverished street singer Albert (Albert Prejean) yearns for beautiful Romanian immigrant Pola (Pola Illery). Pola's boyfriend, local hoodlum Fred (Gaston Modot), grows jealous of Albert's constant attention to his woman and frames the hapless musician for one of his own petty crimes. But while Albert is in prison for Fred's misdeed, Pola ends up falling for Albert's faithful best friend, Louis (Edmond T. Gréville).
