Kenan has been saving up all year to buy a Christmas present for himself: the world's coolest mountain bike. To get the last few dollars he needs, he accepts a job filling in as a department store Santa after the other Santa meets with an unfortunate accident. Excited about finally being able to afford the bike, Kenan is thrown into turmoil when he meets a little boy who wants nothing for himself, just a bike for his little sister. The little boy inspires Kenan to learn the true spirit of Christmas and giving, and Kenan becomes a real-life Santa for the little girl's family.
