Lingering tensions clash with new hopes in director Jonathan Demme’s ensemble drama set during an idyllic wedding that threatens to descend into chaos with the appearance of the bride’s estranged sister — a volatile and unpredictable girl whose turbulent history of personal crisis and family conflict quickly threatens to take precedence over the happy ceremony. Rachel Buchman (Rosemarie DeWitt) is about to be married to the love of her life, but while the weather outside may be perfect, there’s a storm blowing in. That storm goes by the name Kym (Anne Hathaway). Kym is the family black sheep, and wherever she goes disaster is sure to follow. Now, as friends and family gather together for a memorable day of dining, dancing, and celebration, everyone braces themselves knowing that, at any given moment, old skeletons may be dragged out and dusted off for display by the bombshell who seems to have an acerbic one-liner for every situation, and a flare for drama that could set their family home ablaze. Bill Irwin and Debra Winger co-star.
