Sixteen-year-old Lindsay Deerborne has absolutely no interest in spending Christmas with her family, intending to spend it skiing with her friends instead. With only two shopping days before Christmas, Lindsay gets up the nerve to notify her parents that her whole class is going skiing on Christmas Day and that she is definitely going too. The Deerbornes are not impressed and ask Lindsay to try to be a little less selfish and consider the feelings of others. Lindsay's six-year-old sister Alexis is devastated by the thought of Christmas without her sister, but for Lindsay, Christmas at home is so tedious that nothing can change her mind. Lindsay and her best friend Paige decide to visit the mall to check out this year's Santa and maybe have a laugh at his expense, insulting the old man's taste in clothes and his excessive size. Despite this, Santa requests Lindsay's assistance in changing his look, telling her he needs a makeover to restore the spark in his marriage to Mrs. Claus. Determined to prove her parents wrong about her selfish attitude, Lindsay gets him a new look, designer suit, and a way cool attitude. Impressed by the whole thing, Santa takes Lindsay into his confidence and asks her to help him out on the big night; Christmas Eve. Lindsay agrees to do it on one condition: Santa guarantees Lindsay won't be late for the big ski trip Christmas morning. Together the two dash from roof to roof, piling presents under trees and under the noses of all the sleeping little children. When it finally comes down to Lindsay arriving at her own home, there is a surprise in store when Santa asks Lindsay to make this delivery herself. Lindsay enters her home, only to come face to face with the true spirit of Christmas.
