Humorous, festive sequel as the new Santa realises that there is a clause in his contract which states that he needs a wife, or else he will lose his job. Forced to return to Earth to find love, and also help his son who is on the naughty list, he leaves a temporary replacement to fill in. The new Santa's ideas of how things ought to be run are slightly different from the real Mr Claus, however, and Christmas is threatened again.
