Many residents of The Tides Nursing Home see the past more clearly than the present.  So when Marshall, an elderly patient with Alzheimer’s disease begins to see a mystery woman called Faye, no one pays much attention, including his daughter, Rebecca.  But when she delves into her father’s past, she finds that he was once married to a disturbed and dangerous woman – and he believes that she’s returned.  As sinister and fatal accidents begin to plague The Tides, Rebecca fights desperately to survive the dream of a dead madwoman.
