Reece Canby, owner of the Diamond RC, spent years as a youngster on the nearby Mescalero Apache reservation. By treaty Chief Antone's Mescalero tribe owns the Sentinel Basin. Now this grazing land is desired by Sax Starke and Chelso DeLacca of the Teepee spread in order for them to expand their cattle herd. The first step in their plan is to stir up trouble with the Mescaleros so that the federal government will have to intervene. Dobe and Ponco, Mescaleros Reece has known since childhood, stand accused of cattle rustling by two witnesses, both men employed by Teepee.
