Under Western Skies (1926)

Bob Erskine, the son of a wealthy New York banker, falls in love with Ella Parkhurst, the daughter of an Oregon rancher. Bob goes to work as a fieldhand for the elder Parkhurst and discovers that the Oregon crops may fail because eastern bankers, led by Bob's father, refuse to advance the farmers credit. Bob intercedes with his father, who promises to help the ranchers if Bob wins the steeplechase in the Pendleton rodeo.
