Inside, they find the remains of a large alien creature whose ribcage appears to have exploded from the inside.
On the Nostromo, Ripley determines that the transmission is not a distress signal but a warning.
Dallas and Lambert carry the unconscious Kane back to the Nostromo.
As acting senior officer, Ripley refuses to let them aboard, citing quarantine regulations, but Ash violates protocol by overriding Ripley’s lock and letting them in. Kane awakens and seems healthy, but during the crew’s final meal before re-entering stasis, he chokes and convulses in pain before a small alien creature bursts from his chest, killing him, and escapes into the depths of the ship to molt.
Following standard company policy for such situations, the Nostromo lands on the planetoid and Dallas, Kane, and Lambert head out to investigate, damaging their ship upon landing in dust.
They discover the signal is coming from a derelict alien spacecraft.
