One Christmas Eve a long time ago, a baby crawled into Santa's bag of toys... Raised as an elf, Buddy (Will Ferrell) grows into an adult three times larger than the biggest elf--and realizes that he will never truly fit in at the North Pole. This holiday season, Buddy goes looking for his true place in the world--in New York City. Buddy finds his workaholic father (James Caan)--who's on Santa's "naughty" list, a new mother (Mary Steenburgen) and a 10-year-old brother who doesn't believe in Santa Claus or elves. Here, now, Buddy discovers his destiny--to save Christmas for New York and the world!?
