In March 2020, Belle Burden was safe and secure with her family at their house on Martha’s Vineyard, navigating the early days of the pandemic together --- building fires in the late afternoons, drinking whisky sours, making roast chicken. Then, with no warning or explanation, her husband of 20 years announced that he was leaving her. Overnight, her caring, steady partner became a man she hardly recognized. He exited his life with her like an actor shrugging off a costume. In STRANGERS, Burden revisits her marriage, searching for clues that her husband was not who she always thought he was. As she examines her relationship through a new lens, she reckons with her own family history and the lessons she intuited about how a woman is expected to behave in the face of betrayal.
