White Bull, a young Sioux warrior in the 1800s, passes the mandatory test of manhood by catching taming a wild colt, which he names Tonka. A relative, cruel and jealous, tries to claim Tonka as his own. Annoyed and saddened, White Bull releases Tonka. The horse finds its way to a US cavalry captain and participates in the Battle of the Little Big Horn.
