From the outside, Bay Kennishs (Vanessa Marano) life as the privileged daughter of an ex-pro athlete, John (D.W. Moffett), and his devoted wife, Kathryn (Lea Thompson), is idyllic. But inwardly, shes always felt a little out of place in her family. Even so, nothing could have prepared her for the shock of learning that a hospital mix-up when she was a newborn sent her home with the wrong parents. When the truth comes out and she comes face-to-face with her working-class birth mother, Regina Vasquez (Constance Marie), and her parents biological daughter, Daphne (Katie Leclerc), who is deaf, Bay feels as though her world is spinning out of control. Tensions rise when financial pressures force Regina and Daphne to move in to the Kennishes guest house and newly blurred boundaries suddenly challenge the value systems that each family holds dear.
