 Cardelanche, the son of an Indian chief, returns from the East to find himself rejected by his own people. He is made captain of the U.S. army when he saves a detachment of cavalry from a group of renegate Indians, and further removes himself from his race when he develops a relationship with Miriam (Bow), the daughter of the Fort Remmington commandant. Lieutenant Parkman (Walker) gets into a fight with Cardelanche when Parkman is demoted, while General Custer s troups are slaughtered by Cardelanche s people. Cardelanche decides that his true allegiance is to his own race, and gives up Miriam to return to them.
