Lucas, an out-of-work nuclear scientist, struggles with tension in his marriage after his wife Violet mysteriously terminates her pregnancy without his consent. As Lucas physical health begins to inexplicably deteriorate, Violets behavior grows increasingly bizarre and he seeks clarity from his therapist Dr. Benedict. Exhausted by his job search, strange events begin to occur in the home and his medical condition progressively declines. Benedict recommends they try an alternative therapy, but it only makes matters worse. Lucas questions Benedicts effectiveness as his grip on reality begins to fade. Violets deceitful behavior arouses his ever-deepening suspicions, and after a visit from two mysterious guests, her insidious behavior becomes disturbingly pervasive. Lucas anger and frustration turns to fear as Violets sinister intentions are revealed. Lucas tries in vain to escape the evil web she has spun, but by the time he discovers the truth, it might be too late.
