In this romantic comedy, a journalist who's become too much the life of the party finds a new lease on life in a drug and alcohol treatment center. New York newspaper columnist Gwen Cummings (Sandra Bullock) has a fondness for liquor, a boyfriend (Dominic West) with a similar taste for the bottle, and a party girl image that camouflages plenty of emotional baggage. At the wedding of her sister (Elizabeth Perkins), Gwen's pursuit of a good time goes a bit too far when she topples the wedding cake and steals the bridal party's limousine. The result is a court-ordered, 28-day stay in a rehabilitation facility for drug and alcohol abusers. Gwen's failure to get with the program causes her to butt heads with the clinic's director (Steve Buscemi), but her attitude begins to change when she meets Eddie Boone (Viggo Mortensen), a baseball player trying to deal with his substance abuse problems. Diane Ladd, Marianne Jean-Baptiste, and Azura Skye play Gwen's fellow rehab inmates, and legendary roots rock band NRBQ performs at the wedding reception.
