In this his second starring Western, Republic Pictures' laconic singing cowboy Monte Hale played, of all things, a cartoonist. Hale's popular strip -- "The Adventures of Outlaw, King of Stallions" -- is based on his own observations of a herd of wild horses. Learning that Outlaw is not merely a figment of a cartoonist's imagination, rodeo rider Kay North (Adrian Booth) arrives in Rainbow Valley hoping to capture the animal. Using subterfuge, the girl gains the trust of Monte and his kid sister Clarabelle (Jean Barton) while an associate (Bud Geary) kidnaps Outlaw. Monte and Clarabelle use the comic strip to alert the world of the horse's disappearance, and later Hale's sidekick, Locoweed Larson (Emmett Lynn), spots a rodeo horse looking suspiciously like Outlaw. With the news that Outlaw's absence has caused several mares to be killed by wildcats, a repentant Kay returns the animal to the wilderness. In between saving wild stallions, Hale performs Ridin' Down the Trail, by Eddie Cherkose and Cy Feuer, The Man in the Moon Is a Cowhand, by Roy Rogers, and Ghost Town Jamboree, by Glen Spencer. Formerly known as Lorna Gray, leading lady Adrian Booth would appear in eight Westerns opposite Monte Hale. Like Home on the Range, Hale's starring debut, Man from Rainbow Valley was released by Republic in the company's own color system, Magnacolor (later known as Trucolor).
