Roll on Texas Moon

The owner of the Rams Head Ranch is found murdered on the property of the Whirligig Cattle Syndicate, and tensions between Texas cattlemen and sheep herders threaten to escalate into a full-fledged range war. Roy Rogers is sent in from Chicago to investigate and finds an ally in Jill Delaney (Dale Evans), who has inherited the sheep ranch from her slain uncle. With the two sides preparing for battle, Roy takes a job at the Ram's Head Ranch to get to the bottom of the matter and discovers a devious conspiracy that may put Jill's life in jeopardy.
