Thanks to the unexpected attack of Somnus, the Spirit of Sleep, the Guardians and all the other good Spirits have been asleep for almost 100 years. When they wake, the world has lost all faith and hope in fairy tales and magic. The world is shrouded in clouds and Somnus, the Spirit of boredom, and Misery, have full power and control the world indirectly. North, Bunny, Sandy and Tooth are ready to concede, but Jack will not give in that easy. He finds the last light, a 17 year old girl named Mira, and together they need to bring back the world's happiness and light and convince the Guardians to return to their post.
