Santa's got problems: it's a few days before Christmas and production lags, Mrs. Claus is about to give birth and wants family time, and Jack Frost (tired of second billing) is on probation under Santa's supervision. Santa tries to support his wife by bringing her parents to the North Pole (to preserve the secret of Santa, they must think it's Canada). Santa also brings his ex, her husband, and their daughter Lucy.
Inside the toy factory, Jack makes mischief and hatches a plan to become Santa. With Santa juggling that many snow globes, something is bound to go wrong. But if things get too difficult, Santa can always exercise his option to invoke the Escape Clause. Will he?
