Gene Autry and sidekick Frog Millhouse depart Madison Square Garden and NYC heading west for home in their car and a horse trailer carrying Gene’s horse, Champion. They discover that Ronnie Willoughby, a young boy just off the boat from school in England, has hitched a ride, thinking that Gene and Frog were sent by his father to meet him. Ronnie thinks his father is a big rancher in the west and doesn’t know that his father, Alfred Willoughby, is serving time in San Quentin prison because of a frame-up by the officials of a packing company. To keep the father from testifying against them, the packing company officials, Carter, Jenkins and Martin, have arranged for the boy to be kidnapped. Along the way a runaway bride, Joyce Halloway, and her young sister Patsy join the troupe. Various members of the cast sing and dance their way through The Singing Hills, Gaucho Serenade, Give Out With a Song, Heading For the Wide Open Spaces, ‘Tis Be, Keep Rollin’ and A Song of Sunset before every situation is solved, and Gene gets Joyce, Frog gets Ringeye, the father is cleared and reunited with his UK-accented son and the villains are sent to the Republic Big House.
