A young girl, Flo, tries to be friendly with an old horse kept in the stables of her riding school. She learns that this horse, Augustus, was once a world champion show jumper but is now crippled and bitter. Is it Flo's imagination or is there always the same magpie somewhere near this horse? Little does she know that the two animals are lifelong friends who share a magical secret, and that she is trying to find her way into more than simply the story of a once-famous horse now nicknamed 'peg leg Gus'.
