A man comes to the office of the psychiatric Dr. Sammael claiming to be the demon Asmodeus, the torturer of the 13th level of the hell, and he would like to tell him weird things. He says that he had made a deal with Lucifer to become human again. The Devil told him that he should make his virgin sister, Mary Elizabeth, pregnant on the day that their mother died and she should kill six people and deliver the Anti-Christ, and then he would escape from the pit and be reborn. When Mary Elizabeth gets pregnant, her stressed and abusive sister Catherine does not believe that she is virgin, but their father and former obstetrician Albert Martino examines his daughter and sees her intact. Meanwhile the Church discovers the truth about Mary Elizabeth's pregnancy and sends the priest and former military Father Anthony to spy on Mary Elizabeth. She is dominated by the fetus and forced to kill a truck driver, Lars, who is the lover of her friend Jennifer. However during the ultrasound, she realizes that she is carrying a monster and she asks her father to stop her pregnancy. But it is too late.
