It's Christmas time and Sam and Dean investigate a series of murders where the victims were pulled up through the chimney. Sam realizes they are dealing with a sort of Anti-Santa, a demon with roots in pagan lore. Dean wants to celebrate Christmas the old fashioned way as this is his last, but Sam refuses, not wanting to accept that Dean won't be around next year. Sam flashes back to a certain Christmas when he waited for his father to come home to give him a special gift.
