Set on Christmas night, this film tells a story about Arthur Claus, the clumsy but goodhearted son of Father Christmas, who discovers that Santa’s high-tech ship has failed to deliver one girl’s present.

Everyone knows that, each Christmas, Santa Claus delivers presents to every last child on Earth. What everyone doesn’t know is that Santa accomplishes the feat with a very high-tech operation beneath the North Pole. But when the unthinkable happens, and Santa misses one child out of hundreds of millions, someone has to save the day. It’s up to Arthur (James McAvoy), Santa’s youngest son, to deliver a present to the forgotten tyke before Christmas morning dawns.
