Marian Caldwell is a 36-year-old television producer, living her dream in New York City. With a fulfilling career and satisfying relationship, she has convinced everyone, including herself, that her life is just as she wants it to be. But one night, Marian answers a knock on the door...only to find Kirby Rose, an 18-year-old girl with a key to a past that Marian thought she had sealed off forever. From the moment Kirby appears on her doorstep, Marian’s perfectly constructed world --- and her very identity --- will be shaken to its core, resurrecting ghosts and memories of a passionate young love affair that threaten everything that has come to define her.
For the precocious and determined Kirby, the encounter will spur a process of discovery that ushers her across the threshold of adulthood, forcing her to re-evaluate her family and future in a wise and bittersweet light. As the two women embark on a journey to find the one thing missing in their lives, each will come to recognize that where we belong is often where we least expect to find ourselves --- a place that we may have willed ourselves to forget, but that the heart remembers forever.
