Ellen Ripley has been in stasis for 57 years in an escape shuttle after destroying her ship, the "Nostromo," to escape a lethal alien creature which slaughtered her 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 the terraforming colony Hadleys Hope. After contact is lost with the colony, Weyland-Yutani representative Carter Burke and Colonial Marine Lieutenant Gorman ask Ripley to accompany them to investigate. Still traumatized from her alien encounter, she agrees on the condition they exterminate the creatures. Ripley is introduced to the Colonial Marines and an android, Bishop, on the spaceship "Sulaco".
