Synopsis
Craig Burton, an emergency room doctor, and his young wife, Sherry, are making passionate love when a blinding blue light engulfs them. The next thing they know, it's two hours later. Craig believes that he and his wife have undergone some kind of "alien encounter." Shortly after Sherry discovers she's pregnant but the pregnancy is anything but normal. Craig then teams up with alien abduction expert, Bert Clavell, to unravel the truth. Clavell questions Sherry and uncovers, in horrific detail, that she was impregnated by aliens. Craig is determined to remove the Alien fetus from his wife immediately. Against hospital regulations, Craig and Clavell sneak into the hospital, drug Sherry and wheel her into an operating room. While operating, Craig discovers that fetus has wrapped itself around Sherry's vital organs. Craig realizes that the only way to kill the Alien Fetus and to save his wife is to stop her heart, forcing the Alien to disengage itself from her body. Clavell, videotaping all of this, fears that Craig may kill Sherry. Clavell flees the operating room, leaving Craig alone to destroy the Alien...
