A seemingly stable and happily married woman, Madaline Carr begins to experience a series of intense dreams and hallucinations. As her husband Martin tries to help her work through the situation, she becomes increasingly convinced not only that she was responsible for the death of her younger brother some twenty years earlier but also that her long-deceased sibling has returned and is trying to kill her. Determined to return to the rural area in which she grew up and where her brother died, Madaline finds a different kind of horror in a missing husband and a pair of grizzled trappers.
