A young boy named Nicholas is about to become the next Santa Claus, but must first avoid a crisis that's threatening the magic of Christmas before he can succeed in his new role.

Santa doesn't want to retire, but rules are rules and he must train someone to replace him. The lucky winner, to be chosen from among millions of children, must be named Nicholas, be an orphan and have a pure heart. On the other side of the planet, there is a little boy who is a perfect match, but his lack of self-confidence and fear of heights make him a poor contestant. Will Santa agree to step down, and help his apprentice take his place?
