Two convicts escape from prison in the Wild West and disguise themselves as a horse. Sugarfoot sees the "horse" and falls in love. Later, Woody and Sugarfoot learn about the phony pony, and they try to send the convicts back to jail.
A story of the West in the days when the sheriff was more powerful than the mayor or governor. It tells of the sacrifices made by a sister for a brother and the virile, big-hearted nature of a stage-driver who is made sheriff and solves a mystery that hangs over the lives of two innocent people.
