In this 24th (and last) film in Monogram's "Range Buster" series, cattleman Charley Craig tells U.S. Marshal Claiburn that if something isn't done to stop the burning of property and rustling of cattle, he himself will raise a band of vigilantes. Craig is certain that Jack Hammond, owner of practically everything in town, is trying to gain possession of all the surrounding territory. Hammond has cattle buyer Tex Landers killed, and the money he is carrying to buy cattle from Craig stolen. The body is planted in Craig's barn, and Hammond talks the Marshal into arresting Craig, although Claiburn doesn't really believe that Craig is guilty. Mrs. Craig and her daughter, Laura, send for Craig's friends, the Range Busters. Crash, Denny and Alibi learn of Hammond's plans to burn Craig's ranch and rustle his cattle. They ride away to find the herd being rustled but stop it.
