It's Christmas time and, as Sam and Dean investigate a series of murders where the victims have been pulled up through the chimney, Sam realizes they are dealing with a sort of anti-Santa, a demon with roots in pagan lore.

Sam flashes back to a certain Christmas when he waited for his father to come home and give him a special gift. Meanwhile, Dean knows this is his last Christmas and wants to celebrate the old-fashioned way. Sam refuses, not wanting to accept that Dean won't be around next year.
