Kevin Snowdon is a London-based physics teacher who leans on science to support his obsessive dislike for Christmas (much to the dismay of his wife and children) until his wife schemes a reservation mishap that sends him and his family to the Christmas themed tourist destination of Lapland. His dread turns to disaster, as a confrontation with their rival family (who has it all and is not shy about rubbing it in) coincides with a surreal Santa sighting where time stands still and enables Kevin to overcome childhood trauma and embrace the spirit of Christmas Time.
