Written by Betty Burbridge and Stanley Roberts, the film is about a singing cowboy who takes care of three tough boys sent west from Chicago after their father dies and leaves them a cattle ranch.

[1] Following a shootout with lawmen, cattle rustler Jim "Legs" Barton with his dying words makes the local sheriff and childhood friend, Gene Autry, promise to take care of things for him after he's gone.

Gene sends his sidekick Frog Milhouse to Chicago to bring the children back, and then prepares the ranch for their homecoming, with the help of Peggy Shaw, the local schoolteacher.

While they spy on Gene as he proposes to Peggy at a barn dance, general store owner Frank Welch, Legs's secret partner, leads a cattle rustling raid.
