Sergeant Ben Carter and his men find themselves caught between factions as the cattlemen and sheep ranchers near Coultrie, in New Mexico Territory fight over access to grazing lands for their stock. The cattlemen, led by rancher Harlan Bledsoe, have hired a gang of professional gunfighters under the leadership of Lank Cantrell, a man who has no fear of death and no hesitation about dealing it out. When incident upon incident builds to the point where all-out war is threatened, Ben finds himself challenged to make peace or see the streets of Coultrie run red with the blood of not just the fighters, but innocent bystanders as well.
