Cowboy Blues (1946)

Believing her father, Dusty Jenkins (Guy Kibbee), to be a rich ranch owner, Susan Nelson (Jeff Donnell)), comes to visit him, accompanied by her wealthy fiancée Jerome Winston (Mark Robertsas Robert Scott) and his snooty society mother, Mrs. Winston (Isabel Randolph) billed as her radio character Mrs. Uppington). Dusty, instead of owning the ranch, is actually just one of the hands. The real owner is absent, so foreman Curt Durant (Ken Curtis) and "Big Boy" Stover (Guinn 'Big Boy' Williams)) and the other ranch hands (The Hoosier Hotshots)) engage in a conspiracy to keep Susan and the Winstons from learning the truth.
