International intrigue

Pepe Le Moko (Charles Boyer), a thief who escaped from France with a fortune in jewels, has for two years lived in, and virtually ruled, the mazelike, impenetrable Casbah, "native quarter" of Algiers. A French official insists that Le Moko be captured, but sly Inspector Slimane knows he need only bide his time. The suave Pepe increasingly regards his stronghold as a prison, especially when he meets beautiful Parisian visitor Gaby (Hedy Lamarr), who reminds him of the boulevards to which he dare not return...and who arouses the mad jealousy of Ines (Sigrid Gurie), Pepe's Algerian mistress.
