Matty Roubert). John and his pal Whitey (
Fuzzy Knight)and they eventually arrive at the Williams farm and observe Buddy Williams (
Jimmy Butler) and his sister, Julie (
Mary Lawrence, as they train a yearling named RAinbow. John and Whitey go to work for Mr. Williams (
J. Farrell MacDonald), a tyrant who hasn't smiled since his wife died, and thinks it is a waste of time to train Rainbow, who he thinks is only fit for a plow-horse.
