Marcie Jewel is a successful ad executive who is happy with her life. But while all of her cousins are married and having babies, Marcie is the only one who has passed up marriage and motherhood for the sake of her career. As the family prepares for the big Christmas Eve wedding of Marcie's favorite cousin, Dana (who also happens to be the last of the cousins besides Marcie to get married), Marcie's mom, Stephanie Chandler Jewel, is applying pressure to her daughter to settle down and have children. So she does the only thing she can do: find a fake fiance.
