[1] 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.

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.

Grant gets mixed up in a stage coach robbery and killing and rides back to the ranch with Daggett henchman Red Roper.

On the day of the race, Daggett lures Bill away from "Blue Chip" long enough for a wire to be twisted around the horse's leg at the fetlock.

Bill discovers the wire and now also knows that Daggett is the outlaw leader responsible for his father's death and the hanging of his friend Grant.
