Martha (Elizabeth Olsen) escapes from a cult in rural New York and tries to reintegrate into a normal life with her sister, Lucy (Sarah Paulson). Lucy brings Martha to her Connecticut vacation home, where she and her husband Adam (Hugh Dancy) are trying to enjoy a few days away from their regular lives in the city. Martha constantly experiences chilling flashbacks and begins to lose her grip on reality. As the days pass and Martha's behavior becomes more and more erratic, it becomes clear that her time away from home may have had far more effects on her than initially believed.
