Christmas Eve - and Father Christmas has all his presents ready to deliver to the children. But disaster strikes - his reindeer have gone missing. The race is on to find them. He enlists a young boy called Simon to help and brings his Sleigh to life using a magic spell to make it fly. Together they follow a trail of clues and discover the Reindeer imprisoned at a sinister circus. Now they must work together against the clock to re-unite Father Christmas with his Reindeer before Christmas morning.

Will they do it in time? If not Christmas will never be the same again.
