The old-timers always said that anything can happen when the tamaracks change to autumn gold. It is fall. Someone is stalking Gabriella Kingstone. Her husband is gone and she is alone in the house. On a moonlit night her husband, Leon, navigates the torturous curves winding through the marshy bogs where the tamarack grows. A truck looming behind speeds to within inches of his bumper in menacing spurts. A woman berrying near a deserted farm disappears. That's the same day that mentally challenged Vincent Purcey was in the wrong place at the wrong time. The residents of the small northern Minnesota town of Petrie are traumatized by events, but believe outsiders are responsible. Little did they know that the evil lurked amongst them.
