In a chilling psychological drama from writer-director Sean Durkin, a young woman’s fractured reality begins to blur the lines between past and present. Elizabeth Olsen delivers a breakthrough performance as Martha, who flees a secluded cult in the Catskills and seeks refuge with her estranged older sister, Lucy (Sarah Paulson), and Lucy’s husband (Hugh Dancy). As Martha struggles to reintegrate into a normal life at their secluded lake house, haunting memories of her time under the manipulative sway of the charismatic cult leader Patrick (John Hawkes) violently intrude upon her fragile present. The film masterfully weaves between two timelines, crafting a tense and unsettling atmosphere where the threat may be a memory or something far more immediate. Martha’s paranoia grows, her perception of safety erodes, and the distinction between the oppressive control she escaped and the well-meaning confinement of her sister’s world becomes terrifyingly thin.
