After 57 years in hypersleep, Ripley awakens aboard a medical space station orbiting Earth. She recounts the events of the "Nostromo" but is disbelieved by her superiors in the Weyland Yutani corporation, which has now begun to terraform and colonise the planetoid from the first film. When contact with the colony is lost, Ripley is persuaded to accompany a squad of marines to investigate. They discover the colonists have been wiped out after being directed by the company to secure the derelict ship reported by Ripley. There is only one survivor, a girl named Newt. The aliens vastly outnumber and quickly overwhelm the marines, who fight for survival. Only a handful, including Ripley and Newt, escape.
