After advertising to look for his brother Charles and offering a $5,000 reward, a member of the wagon train gets a response from someone who walks through an Indian party that's pinning them all down. What he finds is not what he expected.
The wagon train is pinned down by threatening Cheyenne Indians. Flint has gone for the Army to provide an escort. While waiting Bije Wilcox walks into camp looking for Francis Mason. Mason has offered a $5,000 reward leading to finding his lost brother. Against advice to not go Mason leaves with Wilcox. Wilcox leads him to a remote site to sit and wait for Medicinie Mark who hates all white men and has never let a live white man leave his presence. Wilcox tells Mason that Medicine Mark is his brother. The Cheyenne take the two men captive and Mason learns that Wilcox told the truth. The brothers were raised in Virginia under an intolerant father. As a boy Medicine Mark was against slavery and was despised by all his friends including his own brother so he feels he has no white family or brother. To prove his love Mason decides to become Medicine Mark's Cheyenne brother by going through their ceremony which involves great pain.—Anonymous
