The Rawhide Mining Company is looking for investors to support their hydraulic mining operations in the area. Radio promotions have drawn the interest of local ranchers. Singing cowboy and cattleman Gene Autry (Gene Autry) opposes the company and warns his fellow ranchers not to invest in it—too many local mines have already failed. After saving teenager Judy Drew (Edith Fellows) by stopping her runaway carriage, Gene meets her sister, Nancy Drew (Louise Currie), who runs the local radio station which features a show sponsored by the mining company. Nancy is pleased to see "progressive ranchers" supporting the mining company and tries to elicit Gene's endorsement, but he remains unimpressed.
