When Santa Claus announces a contest in which one extraordinarily good person will accompany him on his Christmas deliveries this year, the entire world scrambles to be especially nice to one another in hopes of winning. When the winner finally sets forth on his Christmas adventure with Santa, he gets more than he bargained for. For, as he's soon to learn, there are some very naughty stowaways on Santa's sleigh, and they've got more in mind than delivering presents and Christmas cheer to the world. Santa is powerless to stop them. Can one young boy with an overabundance of good will save the world from ultimate evil?
