Trail to San Antone.

Gene Autry is back near the saddle, trying to help out a crippled jockey. Gene is certain that the jockey can ride in the Big Race if the lad can regain his self-confidence. Meanwhile, Gene and comical sidekick Sterling Holloway have another problem on their hands: A rogue stallion has "kidnapped" Gene's prize mare. Piloting a plane, Autry seeks out and locates the stallion.
