France, late 1920s. Lovely and free-spirited, Thérèse marries her neighbor Bernard Desqueyroux, thus joining their respective properties into one vast estate. Bernard tolerates his brilliant, passionate young wife’s strong character and opinions, but she soon finds herself suffocated by the boredom of her provincial life and her husband’s intellectual mediocrity. She dreams of Paris, longs for stimulation and culture and, despite herself, starts to seek a way out. Until the day Bernard gets intoxicated with deadly arsenic… What starts as a mistake turns into an attempt to poison him. Thérèse is found out and, in addition to being disgraced in both her own and her husband’s families, she must face justice for her attempted murder… The heartbreaking torment of an astonishing and superb character, played by French star Audrey Tautou.
