Cast & Crew
On the day that thoroughbred colt Warrior is born at the Benton stables, Lightning, the half-wolf puppy of Cyrus Benton's German shepherd, hides in Warrior's stall and thereby saves himself from being drowned by Benton. Although Lightning and Warrior grow up together as best friends, Benton despises the dog for his "mongrel" blood and eventually chases him into the mountain brush. There, Lightning fights his way into a wolf pack and becomes its unchallenged leader, while under the loving scrutiny of trainer John Woods and Benton's daughter Gloria, Warrior develops into a promising racehorse.
As a wild but fast two-year-old, Warrior attracts the attention of two gamblers, Crane and Mason, who offer Benton $20,000 for the animal. After Benton refuses to sell Warrior, Crane and Bill Donlan, one of Benton's hired hands, conspire to steal the colt and place him in a corral hidden in the rough mountain terrain. John, who has been told by Benton that he lacks the "pedigree" to marry Gloria, takes off on his horse and vows to bring back Warrior, unaware that he is being followed by Gloria.
In the brush, Warrior, who has escaped from the corral and is running with a pack of mustangs, encounters Lightning, and after a tense moment, the two animals become reacquainted. John then stumbles on Warrior at the same time that Bill and Crane do, and as John chases Warrior into a steep canyon and is about to rope him, the thieves shoot him and render him unconscious. Although Bill and Crane attempt to capture Warrior, Lightning alerts the horse and helps him to escape their clutches. After Lightning attacks and bests Crane, he and a revived John are reunited at a nearby creek. Lightning then alerts Gloria to John's whereabouts and takes off to find Warrior. When Lightning locates the colt and sees that he is caught in Bill's abandoned lariat, he returns to warn John. Following Lightning's lead, John rescues Warrior from the canyon and returns him safely to the stables. There, John continues to train the horse and readies him for his first big race. As Lightning, his reputation restored, barks his encouragement from the sideline, Warrior wins the race handily. Impressed with John's abilities, Benton then blesses his relationship with Gloria.
