Eight-year-old Hollade's world changes forever on the last day of school before the winter holidays. She hears her friends talking about Santa Claus and the goodies he has in store for them. Puzzled and intrigued, she rushes home to confront her parents with her questions and demands. She wants what her friends have been promised - the presents, the goodies and the new-found Christmas of her dreams. But her parents have other ideas. They try to reason with her, and they explain why she can't have the dreamy Christmas picture that her friends have painted. This drives a wedge between Hollade and her parents, and she goes to bed upset. She's visited by the most unexpected guest in the night, and they go on an adventure where she realises that the fate of the world, and all the Christmases to come, rests on her shoulders. She finds herself in a battle for good and evil, a battle that she, and only she can fight for the fate of humanity. Win, and she gets to return home and make things right with her parents. Lose, and she kisses her family, friends, and the world as she knows it, goodbye.
