After falling asleep in the medical laboratory, Ripley and Newt awaken to find themselves trapped with the two released facehuggers. Ripley triggers a fire alarm to alert the marines, who rescue them and kill the creatures. She accuses Burke of releasing the facehuggers to impregnate her and Newt, allowing him to smuggle the embryos through Earth's quarantine. The power is suddenly cut, and aliens attack through the ceiling. In the ensuing firefight, the aliens kill Burke, subdue Hudson, and injure Hicks; Gorman and Vasquez sacrifice themselves to stall the horde. Newt is separated from Ripley and captured.
