Luke Sanders is a line rider in for a big surprise and a lot of action. On his way into the Arizona high country to stay for the winter, he encounters a band of rawhiders that have just murdered a rancher. When Luke drives them off and gets to the line shack, he finds the man's wife and baby living in it. That is the least of his worries, however, because of the blood feud that has been created between him and the vicious clan. Exciting from start to surprise ending.
