Cast & Crew
Lon Chaney Jr.
When ranch owner Stevens is shot by his greedy partner Martin, his last request is for cowboy Gene Autry to take care of his daughter Lou Ann. Lou Ann, who was trampled by a horse during the barn fire that Martin started after killing Stevens, is paralyzed. Unsuspected in Stevens' murder, Martin befriends Lou Ann, hoping to gain possession of the secret gold mine beneath the ranch. To raise $10,000 for Lou Ann's spinal surgery, Gene takes a job with Covered Wagon Coffee Company and travels in a caravan equipped with radio equipment, broadcasting a Covered Wagon Coffee show to small towns in the West. When Gene stages an amateur singing contest in his home town of Plainesville, Helen Blake, the daughter of his boss Henry, auditions without her father's consent. Concerned, Blake sends Helen's aimless fiancée, Herbert Trenton, after her. With only two days until Lou Ann's surgery, Gene receives a bank advance on his radio contract, but Martin steals his wagon and sabotages his reputation. Meanwhile, Helen, who was hiding in the wagon when it was stolen, sends an "S.O.S." over the radio, and Gene is able to locate the wagon and save her. After Martin's gang follows the couple into town and is arrested, Gene collects Trenton's reward for Helen and has enough money for Lou Ann's operation. Believing Gene's interest in her was purely mercenary, Helen goes back to Trenton. Next, Gene captures Martin and he, too, is arrested after his men reveal his guilt in connection with the secret gold mine. After performing in the recovered coffee caravan, Gene rushes to the Plainesville courthouse and saves Helen from marrying Trenton. As Gene and Helen sing "Rainbow Trail," a recovering Lou Ann looks on.
