This Roy Rogers starrer is set in motion by a range war between ex-partners Brower (William Farnum) and Jackson (Stanley Andrews). Adding to Brower's headaches is the fact that Jackson is a crook who's not above stealing cattle to suit his purposes. When Jackson manages to frame Brower on a trumped-up criminal charge, that's when hero Rogers swings into action. Roy's leading lady this time out is Lynne Roberts, herein billed as Mary Hart, reportedly because Republic wanted its own "Rogers and Hart" team. The 1944 Warner Bros. musical Shine on Harvest Moon bears no relation to this 1939 Republic oater.
