Based on the best-selling novel by English author Ian McEwan, ATONEMENT is an epic love story about Robbie Turner (
James McAvoy), the son of a rich English family's housekeeper, and upper-crust beauty Cecelia Tallis (
Keira Knightley). Robbie, who was sent to Cambridge on the Tallis family's benevolent dime, secretly admires Cecilia. Cee's 13-year-old sister Briony, a fabulist who lives in her own girlish world of plays and poems, harbors a crush on Robbie, which leads her to misinterpret a steamy moment between Cee and Robbie as an attack. Fueled by a shocking love letter draft that Robbie unintentionally sends to Cee, Briony accuses Robbie of an unrelated sexual crime. And suddenly the film, like the book, skips ahead five years, as Robbie -- now an ex-con soldier -- and two other men walk through war-torn France to the pivotal evacuation at Dunkirk. Robbie is just one of tens of thousands of men waiting to get back to England -- with just his letters from Cee and the memory of their stolen embraces to give him comfort. As in the book, as the movie nears its end, viewers meet an elderly Briony, convincingly played by
Vanessa Redgrave, who still wears the same hairstyle and figureless dresses sported by the 13-year-old Ronan. She's finally gotten a chance to fully make up for her adolescent mistakes.
