Saddle Serenade.

Doris Rogers, half owner of a dude ranch, as Jimmy Wakely, "Lasses" White and Dusty Smith to help run it. U.S. Marshal Tom Logan, posing as a stage driver, is killed during a mock holdup of new arrivals to the ranch. Brenda Amers and Horatio Pennypacker, eastern jewel thieves, bring their loot to Roy Williams, who owns the other half of the ranch as a blind for his gang which resells stolen jewels. Vaughn, the desk clerk, re-cuts the jewels in a secret room in the ice house. Fearing he will be caught, Brenda refuses Williams her stolen diamonds and hides them in a bar of soap.
