Lucy wants to be a champion race horse like her Mother and Father. To reach this goal, she decides that she must travel to the Belmont Stakes in Elmont, New York. In preparation for this trip, Lucy decides to study geography. During her geography class, Lucy learns that her travels to Elmont, New York, will take her across Tennessee, Virginia, Maryland, Delaware, and New Jersey. Lucy prepares for the trip both mentally and physically by studying her geography and racing the other colts up and down the fields along Brush Creek. As Lucy journeys to Elmont, New York, she encounters a number of different animals -- an owl, a flock of geese, dolphins, crows, and a covey of quail. Lucy becomes fascinated with the countryside through which she runs, and she decides that in the future she must come back to explore the natural beauty found in these states. Upon reaching the Belmont Stakes, Lucy persuades the race track owner to allow her to run in the place of a sick horse. This break was all Lucy needed to set a race record in winning the Belmont Stakes. After winning this race, Belmont Police inform Lucy that her parents are searching for her. Lucy tells the police that she did not intend to frighten her parents, and she quickly returns home to Tennessee where her victory at the Belmont Stakes is celebrated.
