Tim Allen reprises his role as Scott Calvin, a cynical toy company executive who is forced to take over the job of Santa Claus in the first film. It is now 8 years later and Calvin has got used to the job. But things have started to go wrong; he begins to lose his resemblance to Santa and his son Charlie (Eric Lloyd) has ended up on the 'naughty' list. It transpires that Calvin's contract stipulates he has to have a Mrs Santa and so he sets off to find one, leaving a duplicate Santa the Elves made to cover for him. However, things are not that easy as Calvin finds women are not flocking to date a large, white-bearded man from the North Pole, and the duplicate Santa has begun to play up and may not give up the role.
