Serial killers are on the loose in this "Lone Rider" entry from PRC reportedly based on the exploits of a real-life 1870s roadhouse operator. A couple of crooks, Ben Gowdey (Ray Bennett) and Grogan (I. Stanford Jolley) have repeatedly sold the Circle C Ranch to unsuspecting buyers, whom they summarily rob and kill before signing the papers. Enter Fuzzy Jones (Al St. John), whose cousin Luke was one of the unlucky would-be ranchers, and Rocky Cameron, alias "The Lone Rider," who goes undercover as a fellow outlaw to catch the murderers.
