All is not well on Piffle World. The magical land's most popular sporting event--a race for lightweight aircraft called dragonflies--seems to have been rigged by one of the contestants. But winning the competition is the only way Princess Sakura and her friends can recover one of her precious and powerful memory feathers. The five friends are determined to cross the finish line first, but the cheating is taking its toll--even Fai is out of the running! Can the travelers still win the race and discover who's behind the booby traps before it's too late?
