In 1868 Arizona Territory, a warpath is unleashed by Cochise and his Apaches, prompting Army Captain Bruce Coburn to escort homesteaders to safety. When a consignment of rifles meant to defend them against the Apaches is stolen by greedy white traders and mutinous soldiers, including corporal Bodine, who betrays Captain Coburn's trust, the soldier must single-handedly track down the stolen guns and lead a daring rescue mission to save his men and bring justice to those who have betrayed him.
