Rise of the Guardians

Jack Frost awakens from a frozen pond with amnesia. Upon realizing no one can see or hear him, he disappears. Three hundred years later, Jack, as the young Spirit of Winter, enjoys delivering snow days to school kids, but resents that they do not believe in him. At the North Pole, the Man in the Moon warns Nicholas St. North that Pitch Black is threatening the children of the world with his nightmares. He calls E. Aster Bunnymund/Bunny, the Sandman, and the Tooth Fairy to arms. They are told that Jack Frost has been chosen to be a new Guardian, and Bunny brings him to the North Pole. North explains to Jack that every Guardian has a center, something they are the Guardian of, but a call for help from Tooth's fairies ends the conversation.
