"There were accidents and there was madness and the sea is unrelenting." So says Egan Andrews to his cousin Molly, who has come to live in the family's ancestral home following the death of her father. Plagued by memory lapses brought on by grief, troubled by another cousin's tales of the family legacy - a legacy of drowning - Molly has begun dreaming the dreams of another woman, a woman a hundred years dead. Fearing she is descending into the same madness that claimed her aunt and drove her to suicide, Molly becomes convinced that the legacy and the haunting presence of the long-dead woman are intricately connected; can she find the connection and put the spirit to rest before yet another member of the Andrew's family is swallowed by the waves?
