It's supposed to be a happy day at the Magic Kingdom—the return of the teenaged holographic hosts. But things go very wrong when a sudden lightning storm disrupts the celebration, and Amanda's mysterious sister, Jez, disappears. The only clue is the sighting of a wild monkey in the Magic Kingdom during the storm. The mystery deepens as Finn is contacted by Wayne, an old man he hasn't heard from in months. Wayne tells Finn that there's trouble at the Animal Kingdom: the evil Overtakers have gained control of one of the computer servers that will be used to operate Daylight Holographic Imaging there. That means that if any of the holographic hosts fall asleep, they will go into comas—permanently.
