On her fifth journey to the magical Fairy Realm, Jessie, travels on her birthday all the way to the end of the rainbow and tries to help her new friends, the rainbow fairies.
During her most recent visit to the Fairy Realm, Jessie inadvertently allows a baby fairy to be captured by water sprites who want to hold the child captive until their missing moonstone is returned.
Jessie returns to the magical world where her grandmother was born, where she deals with some griffins, dances with fairies, and borrows something to help her dance in her school concert.
