Scott Calvin has been Santa Claus for the past eight years, and his loyal elves consider him the best Santa ever. But Santa's world is turned upside down when he's dealt a double whammy of bad news: not only has his son, Charlie, landed on this year's naughty list, but if Scott doesn't marry by Christmas Eve - just a month away! - he'll stop being Santa forever.
