Not your typical western, this film features Black - a powerful and cunning, wild stallion who is the leader of a heard. Horse rancher, John Fielding is the father of two grown children. A son, Boyd, who is not very bright, and a daughter, Mary, who cowboy Billy Blair is smitten with. Fielding's head ranch hand, Galvin, has been forcing the son to help him steal Fielding's horses. Blair is determined to capture the clever and agile Black but many men have tried and he has scorned. Black admires Blair's tenacity. Cowboy and horse ultimately form a common bond during a forest fire as Black is trapped and Blair risks his own life to show him the way out. The hunter has now become the rescuer. Black is now devoted to Blair. Producer Hal Roach, best known for his films starring Laurel and Hardy, Our Gang, Charley Chase, Harold Lloyd and Snub Pollard dabbled in westerns during the last years of silent films and King Of The Wild Horses is one of his best.
