 After a cavalry group is massacred by the Cheyenne, only two survivors remain: Honus, a naive private devoted to his duty, and Cresta, a young woman who had lived with the Cheyenne two years and whose sympathies lie more with them than with the US government. Together, they must try to reach the cavalry s main base camp. As they travel onward, Honus is torn between his growing affection for Cresta, and his disgust for her anti-American beliefs. They reach the cavalry campsite on the eve of an attack on a Cheyenne village, where Honus will learn which side has really been telling him the truth.
