Their leader, Rankton the Ruthless thinks she can lead him to the Medallion of Tiben which will give him power over all the creatures of the land. Will the girls be able to outsmart Rankton? If the soldiers do catch them, will Isabella lead them to the necklace in order to save Porkita's family, even though it means giving Rankton unlimited power? Follow the two young princesses on their exciting adventure as they meet up with old friends like Grammy and Inius and meet new challenges that are even more frightening than the ones Isabella faced in The Glass Cage.
