Arizona cowboy Coot Cadigan travels to San Francisco and runs into Stuffy McGee, a small-time crook who stages phony "fights" to amuse the tourists. During one of those frights a man is killed and Coot gets blamed for it. Stuffy hides him out, but when he gets arrested Coot hightails it back to Arizona. with Stuffy's three children. To earn some money, he enters the Arizona Sweepstakes, a horse race with a large purse and one on which Col. Savery--the father of the girl Coot loves--depends on to save his ranch.
