THE MASSIVE SPACE-TUG NOSTROMO GLIDES SILENTLY THROUGH SPACE.

Back from the outer reaches of the galaxy, it's taking its seven-member crew back to Earth. But when the ship's computer receives a distress signal from a nearby planetary system, it rouses the crew from their cryo-sleep. It isn't until after the Nostromo has landed on a barren planet named LV-426 and three crewmembers have gone out to investigate a huge derelict spacecraft that the signal is deciphered and found to be a warning. But one crewmember has already experienced a shocking face-to-face encounter with an alien creature while inspecting an egg-shaped pod. And so the horror begins — a horror which will end the lives of six crewmembers and alter the life of the seventh forever.

AFTER ESCAPING FROM THE NOSTROMO SECONDS BEFORE ITS DESTRUCTION, RIPLEY FLOATS IN SPACE FOR 57 YEARS.

When her escape pod is finally picked up by a deep space salvage team, Ripley is taken to a space station in Earth orbit only to learn that LV-426 has been colonized. Since the colonists have never encountered any aliens in the twenty years they have been on the planet, Ripley's story of the alien and the fate of her fellow crewmembers is met with disbelief. But then communication with LV-426 is lost. The Company contacts Ripley, promising to reinstate her flight license if she accompanies a team of high-tech Colonial Marines back to the planet. At first Ripley refuses. But she ultimately realizes that the only way to banish the nightmare that awaits her every time she closes her eyes is to confront it head on.

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 in the ship's escape pod. But she is not alone for long. She has crash-landed on Fiorina 161, a bleak planet inhabited by former inmates of a maximum security work-correctional facility. When she begins to suspect that an alien may have also been a passenger in her escape pod, Ripley is shocked to discover the inmates possess no advanced technology or modern weapons. Yet the biggest shock is yet to come, for the alien Queen's reaction towards her has Ripley fearing that an old terror has just taken on an even more frightening new dimension.

TWO HUNDRED YEARS HAVE PASSED SINCE RIPLEY MADE THE ULTIMATE SACRIFICE ON FIORINA 161.

Over those intervening years, and after seven horrific failures, scientists have finally managed to clone a perfect replica of Ripley — a replica which includes the alien Queen growing inside her at the time of her death. And since the Ripley clone is so perfect, the scientists decide to keep her alive for study as well. But the new breed of alien born from Ripley's Queen is far more clever than its predecessors — an unfortunate fact the scientists don't realize until after the ragtag crew of The Betty arrives with additional nourishment for the aliens in the form of a hijacked crew of humans.
