Gene heads South in a fiesta of melody and a jamboree of romance. He fights for the right of rancheros to live on their rancho. Outlaws fear him and senoritas cheer him, and his famous horse Champion.

Gene is hired to be foreman of the Big Sombrero ranch by Jim Garland, who is handling all the business affairs of the owner, Estrellita Estrada, who is more interested in going to America than taking care of her Mexican holdings. Gene, discovering Garland's plan to run all the Mexican rancheros off the ranch, turns against his boss and shortly finds himself in the middle of cattle stampedes and an avalanche started by Garland's men.—Doug Sederberg <[email protected]>
