印第安酋长的儿子卡德兰彻从东方回来，发现他被自己的部落抛弃了。当他从一群叛离的印第安人手中救出一支骑兵分队时，他被任命为美国陆军上尉，当他与雷明顿堡司令的女儿米瑞安发展关系时，他又进一步退出了自己的种族。帕克曼被降职后，帕克曼中尉与卡德兰彻发生了冲突，而卡斯特将军的部队则被卡德兰彻的人屠杀。卡德兰彻最后明白他真正的忠诚是对他自己的种族。

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 renegade Indians, and further removes himself from his race when he develops a relationship with Miriam, the daughter of the Fort Remmington commandant. Lieutenant Parkman (Walker) gets into a fight with Cardelanche when Parkman is demoted, while General Custer's troops 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.
