An imaginative boy called Vetle, lives in a world where Santa Claus really exist, and that he lives at the North Pole. This is at least what Vetle himself believes in. Unfortunately Vetle is the only one in the world who still believes that Santa Claus is real.
This is obviously bad news for Santa Claus, who has begun to realize his fading position. He has been forced to lay off all his staff due to the lack of submitted wish lists and hence lack of assignments. Actually there’s only one gift he has to deliver, namely, the one for Vetle.
The clock is ticking; Santa Claus needs to find Vetle before his view is tainted by the grown-ups opinion over the reality of Santa Claus. So with the help from Rudolph the Reindeer, Santa Claus has to go on his most important journey of his life. He must find Vetle, deliver the mysterious gift and convince Vetle that he exists before it's too late and he ultimately fades away.
