This melodrama tells the tale of a great battle between the French Foreign Legion and the rebellious Arab tribe, the Tuaregs, who fight it out upon the blistering Sahara sands. Just before the Legionnaires embark upon their dangerous mission, the commander discovers that he is being cuckolded by his lieutenant. Because the mission is urgent, there is no time to fight over the commander's wife. Unfortunately, as they travel, the tension between the two mounts and they begin squabbling over how to plan the attack. Their inability to work together results in tragedy.

Director: Charles Marquis Warren
