Three children are banished by the Night Fairy to a deserted island for frequent fighting with siblings. There, they have nothing but their wits to find a way home. In the course of their adventures, they voyage onboard a one-of-a-kind ship, where they get stuck in the timeline, beat a sea monster, get the better of Godzilla in human form, win over a spaceship, fight pirates and meet a number of fascinating characters including an army of leprechauns, a fire-spewing dragon, a knight astride a lion, King Midas, and the Night Fairy herself.
