The 2007 film Atonement is a haunting exploration of how a single, impulsive lie can shatter lives across decades [1, 3]. Directed by Joe Wright and based on Ian McEwan’s acclaimed novel, the story begins in the heat of a 1935 English summer [2, 3]. Briony Tallis, a thirteen-year-old with a vivid imagination and a budding talent for writing, misinterprets a private moment between her sister, Cecilia, and the housekeeper’s son, Robbie Turner [1, 2]. Driven by confusion and a sense of moral righteousness, she accuses Robbie of a crime he didn’t commit—a choice that sends him to prison and eventually to the front lines of World War II [2, 4].
