The Weavers ask the Bird-Kersees to hide the multitude of Christmas gifts they've purchased for Amber, Max and Abby. But when Marty and Debbie are put off by their kids' entitled attitude towards the holiday, they decide to return all the gifts and put the money toward a family vacation where they can focus on the true meaning of the holiday. There's just one problem: Larry Bird has opened one of their gifts, spawning a frenzy of gift opening among the aliens and leaving the Weavers with no gifts and no way to pay for the trip. Can alien "Scrooge" Larry Bird save Christmas for the Weavers?
