Atonement

In Atonement, three children lose their innocence, as the sweltering summer heat bears down on the hottest day in 1935, and their lives are changed forever. Cecilia Tallis is of England's priviledged class; Robbie Turner is the housekeeper's son. In their moment of intimate surrender, they are interrupted by Cecilia's hyperimaginative and scheming 13-year-old sister, Briony. And as chaos consumes the family, Briony commits a crime, the guilt of which she shall carry throughout her life.
