On a sultry summer day in 1935, an upper-class British family prepares for a dinner party at their country estate. The players: Briony Tallis (newcomer Saoirse Ronan), a precocious preteen writer; her older sister Cecilia (Keira Knightley), Cambridge graduate and femme fatale; Robbie Turner (James McEvoy), the housekeeper's mensch-y son, who carries a torch for Cecilia; and various visitors and family members. A series of misperceptions, fueled by the summer heat and Briony's childish hurts and fevered imagination, lead to a dramatic false accusation that lands Robbie in jail. We meet all three characters five years later in the thick of World War II, as foot soldier Robbie prepares for the Dunkirk evacuation and the two estranged sisters train as nurses in London.
