George Banks (Steve Martin) and his wife, Nina (Diane Keaton), are the proud parents of Annie (Kimberly Williams), but when she returns from studying abroad and announces that she's engaged, their whole world turns upside down, especially that of overprotective George. From meeting the in-laws to wedding plans with an over-the-top consultant (Martin Short) and his flamboyant assistant (B.D. Wong), it seems as if the troubles never end in this update of the classic Spencer Tracy comedy.
