A little sheep named Speedy lives on a beautiful ranch and has adopted Symbol, a racehorse, as her Mom. She practices early in the morning, every day to try to run faster and faster. Symbol leaves the ranch often to run races and one night she doesn't return. Speedy learns that her "Mom" was hurt during a race and may never run again. When Symbol returns Speedy helps her escape the ranch and go to the mountains to heal. When Symbol is strong again, she decides to go back to the ranch and play a trick on her trainer. The jockey takes Symbol out on the track, and she runs fast enough to break the world record thanks to Speedy's dedication and love.
