Outside Dallas, Kane and Lambert continue the search
While attempting to land on the barren planet, the vessel has engine trouble and must remain on the surface for repairs. Three crew members -- Captain Dallas, Executive Officer Kane, and Navigation Officer Lambert -- set out to investigate the derelict ship. During their expedition, Ripley discovers that the transmission is a warning, not an SOS.
While searching the ship, Kane encounters a cargo hold filled with eggs. Upon investigation, the egg launches a parasitic organism that attaches itself to his face. When the others take the comatose Kane back to the ship, they discover they cannot remove the parasite without killing him. Several hours later, the parasite dies and Kane awakens. Life seems back to normal on the Nostromo until the parasite inside his body launches itself out of his chest. Kane dies a painful and torturous death as his crew mates watch on in horror. The crew attempts to hunt down the small alien, but it has a surprise for them. The small somewhat frail chestburster has rapidly grown to an eight foot tall killing machine. After Brett's remains are found, they know that something much larger was the cause. The tables are turned, and hunters become the hunted as the alien systematically kills them. At this time, the crew discovers the Company's plans to bring back the alien for their Bio-Weapons Division by any means necessary. Ash, the Science Officer orchestrates this attempt, and even attempts to kill his fellow crew mates.
Lt. Ripley, the last surviving crew member sees only one way out. She must destroy the Nostromo with the alien onboard. She sets the self-destruct on the Nostromo and escapes in a shuttle, but there will be one last battle. The alien has stowed away aboard the shuttle, and in the final face off, she blows it out of the airlock.
