MacMurray portrays the Utah cowboy whose bond with his horse Smoky was immortalized in Will James' classic tale. The cowboy captures and trains the wild horse but during a cattle raid is separated from it. It's not until years later, after the horse has been mistreated by others, that the
two are reunited. This is best of the three versions of the story, which also made it to the screen in 1933 and 1966. Musical numbers include well-known folk and cowboy songs such as "The Foggy, Foggy Dew," "Blue Tail Fly," and "Woolly Boogie Bee."
