Nosotromo is a commercial mining vehicle returning to earth. Tom Skerritt as Captain Dallas, Ian Holm as a creepy science officer, Yaphet Kotto as an excitable mechanic, Veronica Cartwright as navigator Lambert, and Harry Dean Stanton as comic relief. Ripley provides the voice of reason- rejected by the actions of her crewmates. For most of the crewmembers, the work is drudgery and all they look forward to is returning home and collecting their money. In Nosotormo s decent towards earth, Mother -the ship s computer, receives a signal from a downed spacecraft.
Mother alerts all seven crewmembers to wake up.
From here, Dallas, Kane, and Lambert head toward the downed spaceship to investigate. Inside the spaceship they find a chamber full of egg looking objects. As Kane examines one of the eggs, it rips a hole through his protective helmet and forces a proboscis down his throat. Lambert and Dallas take his body to the ship where Ripley refuses it come aboard because of regulation violation. However, Ash lets them in and Kane is taken to the medical lab where Ash determines it would be too dangerous for the life form to be removed from Kane.
