Rawhide Rangers

One of the most recycled plots of the B-western genre in which a friend/brother of a lawman/Ranger/Mountie is killed by a gang of outlaws, and the lawman/Ranger/Mountie quits his job (as a ruse), turns outlaw (in a fashion) and joins the gang to bring them to justice. Columbia alone made two versions with Buck Jones and also used it for Charles Starrett and Russell Hayden later on.
