After surviving the accident that took her mother's life, Claire Broussard worked hard to escape her small Louisiana hometown. But these days she feels something lacking. Abruptly leaving her lucrative job in Chicago, Claire returns home to care for her ailing grandmother. There, she unearths a beautiful sculpture that her great-grandfather sent home from Paris after World War II. At her grandmother's urging, Claire travels to Paris to track down the centuries old mask-making atelier where the sculpture, known only as L'inconnue, or the Unknown Woman, was created. With the help of a passionate sculptor, Claire discovers a cache of letters that offer insight into the life of the Belle Epoque woman immortalized in the work of art. As Claire uncovers the unknown woman's tragic fate, she begins to discover secrets, and a new love, of her own.
