Horse trader Roy Rogers has plans to breed his prize mare with legendary stallion Golden Sovereign. Unfortunately, scheming nightclub owner Brett Scoville (Jack Holt) has his eye on the same stud and steals the horse. Sovereign breaks free, however, and mates with Rogers’s mare, eventually producing a spirited colt that Rogers names Trigger. When Sovereign is accidentally killed, Rogers is blamed for the crime, and he and Trigger must escape the law and track down the real killer.
