Gaucho Serenade

Gene (Gene Autry) and Frog (Smiley Burnette) are on a train bound for California when they meet Ronnie (Clifford Severn), a young boy hiding from kidnappers. Ronnie thinks his new friends work for his father, Frederick (Lester Matthews), who he says owns a cattle farm named "Rancho San Quentin." Gene and Frog realize the boy's father is in San Quentin Penitentiary, but decide to keep it quiet. When Frederick shows up after a daring jailbreak, Gene and Frog help him clear his name.
