Baroud plot
André Duval and Si Hamed are both sergeants in the Spahis, the corps of the Algarian Foreign Legion in the French army. Duval falls in love with Si Hamed's sister Zinah, despite the fact that an unbeliever's attention could mean her death. Zinah's father, Si Allal, is a Berber chieftain who finds himself at odds with the bandit Si Amarok, who lusts after Zinah and plans to betray Si Allal. The Spahis defend him from the bandits, while Duval and Zinah bring out their feelings. When the Spahis leave, however, he is with them and she waves him goodbye.
