Focus Features has just released 3 teaser posters for their upcoming Joe Wright-directed film Atonement, starring Keira Knightley, James McAvoy, and Saoirse Ronan.

Atonement, which hits theaters on December 7, 2007, was written by Christopher Hampton based on the novel by Ian McEwan.

See the three new poster images here after the jump, along with the official synopsis.

At first glance, this movie might appear like the same old period romance piece rehashed. Even the filmmakers (including Wright, who directed Knightley in Pride & Prejudice) have labeled it a “British romance.” But, judging by the synopsis and the previously posted trailer and movie clips, it seems like much more. Yes, there is a romance between Knightley and McAvoy’s characters, but there’s also the false accusation a young girl (Saoirse Ronan) makes and the consequential damages it has on all three of their lives.

Official Synopsis

Joe Wright, the BAFTA Award-winning director of “Pride & Prejudice,” has reunited with his filmmaking team and his Academy Award-nominated actress, Keira Knightley, for another classic British romance, starring James McAvoy (BAFTA Award nominee for “The Last King of Scotland”) opposite Ms. Knightley. Christopher Hampton (Academy Award winner for “Dangerous Liaisons”) has written the screenplay adaptation of Ian McEwan’s best-selling 2002 novel Atonement. Shot on location in the U.K. , the film’s story spans several decades. In 1935, 13-year-old fledgling writer Briony Tallis (Saoirse Ronan) and her family live a life of wealth and privilege in their enormous mansion. On the warmest day of the year, the country estate takes on an unsettling hothouse atmosphere, stoking Briony’s vivid imagination. Robbie Turner (Mr. McAvoy), the educated son of the family’s housekeeper, carries a torch for Briony’s headstrong older sister Cecilia (Ms. Knightley). Cecilia, he hopes, has comparable feelings; all it will take is one spark for this relationship to combust. When it does, Briony – who has a crush on Robbie – is compelled to interfere, going so far as accusing Robbie of a crime he did not commit. Cecilia and Robbie declare their love for each other, but he is arrested – and with Briony bearing false witness, the course of three lives is changed forever. Briony continues to seek forgiveness for her childhood misdeed. Through a terrible and courageous act of imagination, she finds the path to her uncertain atonement, and to an understanding of the power of enduring love.
