Synopsis:
After his brother, Tex, wires him about the discovery of a diamond mine in South Africa, Gene Autry decides to help, leaving Texas with an urgently needed shipment of horses. Gene arrives in Dunbar, South Africa, with Frog Millhouse and discovers that Tex is missing, charged with the killing of his partner, Edward Barclay. John Cardigan, sinister owner of the Dunbar saloon, returns a cablegram Gene wired to his brother. Noticing that it has been opened and resealed, Gene decides to watch Cardigan. Gene's suspicions are substantiated when he spots Cardigan's native employee wearing Tex's belt. Cardigan frames Gene and Frog for illicit diamond buying, and then heads for the diamond mine with saloon singer Gwen, who is Barclay's daughter incognito, seeking to find her father's murderer. Gene and Frog elude the police and reach Cardigan's party, but the entire group is captured by savage natives. All but Cardigan and Frog are released, however, because Frog performs magic tricks and teaches the chief's children how to sing. Gene, Gwen, and her English friend Barkey, enter the Valley of Superstition. They find the diamond mine, only to discover Cardigan has escaped the natives and is awaiting them. Gene sees Tex in the mine's chain gang and fights his way free from his cell. Frog then arrives with the Cape police, who released him from his unwilling job as Royal Music teacher. Cardigan meets a just death after a furious fight with Gene.
