Buck Cannon jeopardizes his life, when he tries to turn two Apaches into wranglers. Sourdough and Saddleblanket quickly become valuable hands. When an Apache war party kills three ranchers and kidnaps the two Indian wranglers, all but Buck believes the two Apaches are killers and have reverted to their old ways. The High Chaparral group tracks the war party to an Army fort the Indians have captured and where Buck lies seriously wounded beyond reach of his comrades. Almost dying of thirst, Buck's only chance for survival lies in an appeal to his Indian wranglers inside the fort to turn on their fellow Apaches.
