It's 1962, in the Suffolk countryside of England, and the Devereaux family is prospering and happy.
But Evelyn has a secret she's never told her beloved husband, Kit. Hope, Kit's sister, has never felt completely secure in her happiness, despite her loving husband, Evelyn's brother Edmund, her successful career writing children's books, and her adopted daughter, Annalise. Julia, married to the oldest Devereaux sibling, Arthur, has been trained most of her life, by her father and new by Arthur, to believe it's her duty to be obedient, and that anything that goes wrong is her fault.
