During the night, one of the sentries is killed, the other seriously wounded, and all their horses are stolen, leaving them stranded. They bury the dead man and put his sword at the head of his grave. One by one, the remaining men are picked off by the unseen assailants. During the course of the film, the men talk and reminisce and fight—and deal with their situation. In desperation, the sergeant sends two men chosen by lot on foot for help, but they are caught and their mutilated bodies returned. One man, Abelson, suffering from heat exhaustion, sees a mirage and wanders into deadly rifle fire. The pilot of a British biplane spots the survivors, but nonchalantly lands nearby and despite frantic warnings is killed. After dark, the sergeant takes the machine gun from the aircraft and then sets the plane on fire as a signal to any British troops. Sanders, a religious fanatic, goes mad and walks into deadly fire.
