Buddy, mischievous son of a race horse owner, is a competent youth around the stable and racetrack. He, Martha and Spec are pals. The day of the big steeplechase Buddy discovers one of the jockeys has been "fixed" by a crooked gambler. The jockey is to ride Buddy's father's horse. Buddy beats up the jockey, temporarily putting him out of commission, and rides the horse himself. With the aid of Martha and Spec he wins, but only after getting a lift in a taxicab.
