A 21 year old virgin wakes up pregnant with a demonic fetus that possesses her and commands her to go on a murderous rampage.

Mary Elizabeth goes to bed alone one night, still a 21 year old virgin, and wakes up the next morning...pregnant. Possessed by the demon fetus growing within her womb, Mary Elizabeth obeys her homicidal cravings to kill...for the sake of her unborn spawn. Mary Elizabeth's dark transformation, controlled by her unborn demon child, is driven by its dark cravings. Once the child is born there will be hell on earth. From this apparent immaculate conception comes edge of your seat terror.—Anonymous

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.—Claudio Carvalho, Rio de Janeiro, Brazil
