At 70 minutes, the Roy Rogers musical western Idaho was packaged and promoted as a "special," rather than just another B-flick. The story concerns the efforts by kindly judge Grey (Harry Shannon) to establish a "Boy's Town"-style establishment for wayward youngsters. The judge is opposed by gambling-house proprietress Belle Bonner (Ona Munson), who is a prositute in everything but name. Belle hopes to discredit Grey by revealing the judge's criminal record, but state ranger Roy Rogers comes to the rescue. The climax finds Rogers, heroine Terry Grey (Virginia Grey) and the ex-delinquent kids (played by members of the Robert Mitchell Boy Choir) capturing Belle's bandit gang. Gabby Hayes, Roy Rogers' former sidekick, is conspicuous by his absence in Idaho; Hayes was replaced on this occasion by the ubiquitous Smiley Burnette, as always cast as "Froggy Millhouse."
