At Tomten's home in the North Pole, preparations are underway for Christmas. The snowman and the elves don't have wish lists, so Santa's workshop only runs at half speed. The problem is that people in the ordinary world have stopped believing in Santa's existence. And if everyone stops believing in Santa, the lamp of light goes out and the world of Santa comes to an end. Santa needs to pull himself up quickly and Mother Santa and the whole family are fighting to get Santa back on track, before it's too late.
