Father Christmas doesn't want to retire, but the rules are formal: he must chose an apprentice who will replace him. Selected from among millions of children, the lucky candidate must be called Nicolas, be an orphan, and have a pure heart.

One the other side of the world, a little boy perfectly meets these criteria, but his lack of self-confidence and his attacks of vertigo make him a poor candidate.

Wil Father Christmas accept to hand over the reins and help his apprentice take his place?
