Koningin Aggravain heeft bepaald dat niemand mag trouwen totdat haar zoon, prins Dauntless, is getrouwd. Ze is er echter in geslaagd om elke prinses die langskwam te saboteren. Wanneer Sir Harry en Lady Larken te horen krijgen dat ze ouders worden, getrouwd of niet, gaat hij naar de moerassen en brengt prinses Winnifred (“Fred” voor haar vrienden) mee terug.
