Santa Claus does not exist. Or does he? For onedoubting boy (voice of Daryl Sabara and Tom Hanks), an astonishingevent occurs. Late on Christmas Eve night, he lies in bed hoping tohear the sound of reindeer bells from Santa's sleigh. When to hissurprise, a steam engine's roar and whistle can be heard outside hiswindow. The conductor (voice of Tom Hanks) invites him on board to takean extraordinary journey to the North Pole with many other pajama-cladchildren. There, he receives an extraordinary gift only those who stillbelieve in Santa can experience.
