Aliens is a 1986 science fiction action film written and directed by James Cameron. It is the sequel to the 1979 science fiction horror film Alien, and the second film in the Alien franchise. The film is set in the far future; Sigourney Weaver stars as Ellen Ripley, the sole survivor of an alien attack on her ship. When communications are lost with a human colony on the moon where her crew first saw the alien creatures, Ripley agrees to return to the site with a unit of Colonial Marines to investigate. Michael Biehn, Paul Reiser, Lance Henriksen, and Carrie Henn feature in supporting roles.
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. 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 by her alien encounter, she agrees on the condition that they exterminate the creatures. Ripley is introduced to the Colonial Marines on the spaceship Sulaco but is distrustful of their android, Bishop, due to the android aboard the ''Nostromo'' having betrayed its crew to protect the alien on company orders.
