Rocket is a very naughty pony. Sara desperately wants to win a blue ribbon with Rocket, but the two-year-old colt has grown into a very unruly pony who loves to get into trouble. When it's time to come in from the field, he runs away; he loves to chew on his lead ropes, and he nips at Sara whenever she tries to work him. Convinced that showing Rocket will help him learn to be a good pony, Sara decides to take him to a local horse show. What could go wrong?
