Nellie Sue is taking her cowgirl flair to the county fair! There are animals to pet, and rides to go on. But, of course, Nellie Sue is really looking forward to the Bike Rodeo. She hopes that practicing will make her and her two-wheeled horse good enough to win against the reigning champion and Rodeo King, AJ Pickett. But when a nearby goat gets loose and threatens to ruin AJ's turn, Nellie Sue knows that it's her job as an honest cowgirl to help out.
