US Marshall Luther Killeen is working undercover as a Texan pistolero in Tucson to find proof that the San Pedro Ring, an Arizona trading and freighting business concern, is supplying arms to the bronco Apache in the territory. But the fat is truly in the fire when his real identity is discovered and Clelland Singer the ruthless boss of the Ring, hires a professional killer, part-Sioux Louis Merlain, to hunt down Luther. Now it is a case of kill or be killed. At the conclusion of a dramatic chase there is a bitter showdown between Luther and the half-bred. Will justice prevail?
