The story begins in the nearly deserted Emerald City. Dark clouds hang overhead, damage is apparent throughout the area, and it is clear that something is wrong. The only brave enough to stay are the Scarecrow, the Tin Man, and the Cowardly Lion. All of them are on edge due to recent events, but they have all come together with a common goal, to bring Dorothy Gale back to the Land of Oz and help her save Emerald City. They prepare to use Scarecrow's invention called the Rainbow Mover to summon Dorothy. Unfortunately, things are indeed worse than they believed, as the broomstick of the Wicked Witch of the West was recently stolen from its case and Flying Monkeys are on the loose. As the Tin Man and Cowardly Lion hold the door closed from the Flying Monkeys, the Scarecrow begins to send a message to Dorothy.
