The usual, routine, singing cowboy stuff from Roy Rogers as he is sent to investigate some shenanigans at a ranch on the US/Mexican border. The film really belongs to Andy Devine as "Sheriff Cookie"; the enthusiastic, if not desperately competent local sheriff who alongside trashy-journalist "Lee Madison" (Dale Evans) has to help Rogers get to the bottom of it all. Fritz Lieber adds a wee bit of weight to the proceedings, and if you like songs with your westerns then this is no better or worse than the norm. The story is way too thin for 80 minutes though, an hour would have sufficed.
