Thomas McCabe is on his way to a brilliant career as a lawyer when, in 1837, he gives everything up to take a job with the Bureau of Indian Affairs. Sent to live with a tribe in the wilds of Missouri, McCabe soon saves the life of a young brave. Subsequently, yet grudgingly, he is accepted by the Cheyenne, until he falls hopelessly in love with the beautiful, and betrothed, Night Bird Woman. Determined to marry her, McCabe must prove himself to the tribe. During his initiation, he is visited by a Spirit of Vision that carries a message powerful enough to teach Thomas the true meaning of courage, and to remake the lives of the proud people he will come to call family.
