Ellen Ripley has been in stasis for 57 years aboard an escape shuttle after destroying her ship, the Nostromo, to escape an alien creature that slaughtered the rest of the crew. She is rescued and debriefed by her employers at the Weyland-Yutani Corporation, who are skeptical about her claim of alien eggs in a derelict ship on the exomoon LV-426, since it is now the site of a terraforming colony.
