Set in the fictional town of Thayer, Massachusetts, the story focuses on Meredith Morton Sarah Jessica Parker, a successful Manhattan executive whose uptight, conservative demeanor is a sharp contrast to that of her boyfriend Everett Stone Dermot Mulroney and his liberal and rambunctious family.Meredith, feeling very much an outsider during the Christmas holidays with Everetts family, opts to stay at the local inn instead of with the family and asks her sister Julie Claire Danes to join her for support. Everett finds himself attracted to the more outgoing Julie. Meredith desperately tries to fit in, but her strained attempt to play charades and a clumsy effort to engage the family in a dinner table discussion about nature versus nurture and sexual orientation prove to be disastrous and their father, Kelly Stone Craig T. Nelson, the most understanding of the family, blows up at her. Distraught, Meredith attempts to drive off but crashes the car, and Everetts brother Ben Luke Wilson comes to comfort her. The two end up at a local bar where, after several drinks, Meredith begins to enjoy herself. She invites Amys high school flame and local paramedic, Brad Stevenson Paul Schneider, to the Stones for Christmas breakfast. The following morning, when she awakens in Bens bed, she incorrectly assumes their night of revelry ended with the two having sex together. ........
