Alice-Miranda has a birthday to celebrate, and the village show to look forward to! The highlight of the day is going to be the horse race, but Rockstar the prize racehorse is refusing to leave the stables- until Alice-Miranda introduces him to her own very naughty pony, Bonaparte. Then disaster strikes! Bony is kidnapped - and Rockstar won't compete without him. Can Alice-Miranda find her beloved pony and get him back to the show in time for the race?
