Nebraska farmer’s wife Mary Wilkes is found on a country road miles from her home, in a state of fear and confusion. In California, psychiatrist Dr Neil Chase is asked to treat Leslie Hahn who is experiencing irrational fears, believing that phone linesmen were trying to break into her house. In treating Leslie, Chase uses hypnosis to regress her to the incident, which she has blanked from her memory. She recalls how men with no faces entered her house and she was abducted. Leslie later finds that she is pregnant. In his subsequent dealings with Mary, Chase finds that she had a remarkably similar experience to Leslie. In exploring their stories and those of others, Chase becomes certain that the abductees experienced something for which he has no understanding. However, his insistence in the reality of their experiences also damages his reputation in the psychiatric community. It was partially based on Ufology Budd Hopkins' book Intruders: The Incredible Visitations at Copley Woods.
