Strikingly different since childhood and leading dissimilar lives now, sisters Frances and Cynthia have managed to remain "devoted"—as long as they stay on opposite coasts. When Frances arranges to host Thanksgiving at her idyllic New England farmhouse, she envisions a happy family reunion, one that will include the sisters' long-estranged father. Cynthia, however, doesn't understand how Frances can ignore the past their father's presence revives, a past that includes suspicions about their mother's death twenty-five years earlier.

As Thanksgiving Day arrives, with a houseful of guests looking forward to dinner, the sisters continue to struggle with different versions of a shared past, their conflict escalating to a dramatic, suspenseful climax.
