Ripley is once again awakened from cryo-sleep to discover all is not as it should be. Not only is she no longer on the ship that carried Newt, Hicks and her away from LV-426, she is also once again the only survivor on the ship’s escape pod. But she is not alone for long. She has landed on Fiorina 161, a planet inhabited by former inmates of a maximum security prison. Fear escalates when she begins to suspect that an alien may have also been a passenger in her escape pod. Yet the biggest shock is yet to come, that an old terror has just taken on an even more frightening new dimension.
