Rachel McAdams

Everett brings his fiancé Meredith home to meet his family for the Christmas holiday. It's an instant disaster when Everett's parents, Sybil and Kelly, agree with their gay, deaf son Thad, pot-smoking son Ben and daughters Amy and Susannah that Meredith is way too uptight to be welcomed into their family. Wanting to please Everett and get along with his family, Meredith recruits her sister Julie to help her thaw the Stone family cold front.
