Bent on revenge for the death of his father and the theft of their ranch, young Bill Walton rides into town seeking the aid of his uncle. As he rides into town, he takes a bullet meant for gambler Matt Daggett and across the street lies his uncle, victim of the gambler's gun. Dagget looks on Bill as 'good luck' and nurses him back to health and gives him the job of training "Blue Chip", the fastest quarter horse in the west, for a big race. Bill doesn't know that Dagget plans to fix the race and put his own money on another horse.
Based on the novel "Quarter Horse" by Gordon Young.
