One of the most acclaimed films of recent years, this stunning adaptation of Ian McEwan's novel is a haunting tale of star-crossed lovers and the shattering consequences of a single reckless act.

On an English country estate in the sweltering summer of 1935, 13-year-old Briony Tallis observes her older sister Cecilia with Robbie Turner, the son of their family's housekeeper. A series of misunderstandings leads Briony to accuse Robbie of a crime he did not commit. Her accusation not only destroys Cecilia's and Robbie's newfound love, but irrevocably alters the course of all three of their lives.

Brilliantly and innovatively directed by the award-winning Joe Wright (Pride and Prejudice), including an extraordinary sequence set on the beaches at Dunkirk during World War II—an amazing cinematic feat that both fans and filmmakers will be talking about for years to come—Atonement builds to an unforgettable and emotionally shattering climax. Magnificent performances by all include Knightley's powerful and utterly spellbinding turn as Cecilia; McAvoy's (The Last King of Scotland) riveting and, ultimately, heartbreaking portrayal of Robbie; and sharing the pivotal role of Briony at various stages of her life, young Saoirse Ronan, Romola Garai and Vanessa Redgrave, whose climatic scene will leave you speechless. Atonement is an instant classic.
