Merlin Fanshaw is the "Bodacious Kid." Now, as a young man, he finds himself the proud new owner of a blood-bay thoroughbred race horse. After his parents death, Merlin had been semi-adopted by livery owner Walt Finkleman. But now old Walt is dead and Merlin is alone, except for the prized horse the fine old man had left him. Touched by the inheritance, Merlin sees the horse, Quicksilver, as a chance to change his future. Quicksilver could win him fortune and fame at the racetracks.
