Rancher Gene Autry (Gene Autry) is the leader of the valley ranchers being ruined by the stripping of nearby mountain area of the precious timber. The ranchers face flood devastation unless reforestation is adopted by the Wentworth Lumber Company. Gene and Frog Millhouse (Smiley Burnettte) appeal directly to Asa Wentworth (George Clevand), the owner of the company but find him dominated by his impertinent granddaughter Billie Wentworth (Maris Wrixon) who is in love with the ruthless general manager of the company Larry Drew (Robert Kent.) Old Asa doesn't approve of Drew's logging tactics and secretly helps Gene and Frog concoct an elaborate plot to have Mount Warner declared a state park and wildlife refuge. A severe storm washes her grandfather into a mountain torrent and nearly drowned before Billie sees for herself the devastation caused by the over-logging of the mountain and is won over to the plight of the ranchers.
