The Santa clause

You are a Divorced dad named Scott who has custody of your son, Charlie, on Christmas Eve. After he accidentally kills a man in a Santa suit, you are magically transported to the North Pole, where an elf explains that you must take Santa's place before the next Christmas arrives. You think you’re dreaming, but over the next several months you gain weight and grow an inexplicably white beard. Maybe that night at the North Pole wasn't a dream after all -- and maybe you have a lot of work to do.
