Briony Taliis (Saoirse Ronan) at age 13, lives with her family and older sister in a mansion complete with all the luxuries. Briony is bored though and spends her time getting into everyone elses business, including her sister Cecilia's (Keira Knightley.) Robbie (James McAvoy) is the housekeeper's son, and Briony sort of has a crush on him or at least, thrives on his attention. But Robbie keeps giving that attention to Cecilia. When Briony sees from her window, Cecilia go into the fountain on their estate, removing most of her clothes to do so, she is in shock that Robbie stood before her sister watching. Later, Briony finds the two about to make love in the house library. When a crime is committed in the woods, Briony decides to become a witness and point the finger at Robbie to remove him from his sister's presence.
It does change the situation, that is for sure. So much so, that Robbie is sent away to do time for a crime he did not commit and also be denied his true love Cecilia. Cecilia's heart is never healed and years later when Briony (Romola Garai) is 18, she returns to her sister's side to tell her the truth. But changing the lives of so many people are some things you can never make up for.
