In 1876, White Bull, a young Sioux, captures a wild stallion he names Tonka, and trains him. He must give the horse to his bad-tempered cousin, Yellow Bull, who abuses Tonka to break his spirit. White Bull lets the horse escape, and Tonka is captured by the U.S. Cavalry. Captain Myles Keogh rides Tonka at the Battle of Little Big Horn, and the horse is the only survivor of the massacre. When Captain Keogh is killed Tonka rises up and kills Keogh's killer. White Bull joins the cavalry, and is given the duty of looking after Tonka, who has received an honorable discharge from further battle duties.
