A Sky Atlantic limited series based on the book You Should Have Known by Jean Hanff Korelitz, Grace Fraser (Kidman) is living the only life she ever wanted for herself. She’s a successful therapist, has a devoted husband and young son who attends an elite private school in New York City. Overnight a chasm opens in her life: a violent death, a missing husband, and, in the place of a man Grace thought she knew, only a chain of terrible revelations. Left behind in the wake of a spreading and very public disaster and horrified by the ways in which she has failed to heed her own advice, Grace must dismantle one life and create another for her child and herself.
