The Alien is peering into the cat carrier. Jones looking back.
MOTHER (voice over): The option to override automatic detonation expires in T-minus one minute.
EXT. NOSTROMO: The mother ship.
MOTHER (voice over): 29 . . . . 28 . . . . 27 . . . . 26 . . . . 25 . . . . 24 . . . .
INT. ENGINE ROOM - CUBICLE: Ripley makes it back to the engine room. She rushes to the controls and begins deactivating the self destruct system. The chamber filled with smoke. Ripley breaks out in perspiration from the intense heat. The sirens continue sounding.
MOTHER (voice over): 23 . . . . 22 . . . . 21 . . . . 20 . . . . 19 . . . . 18 . . . . 17 . . . . 16 . . . . 15 . . . . 14 . . . . 13 . . . . 12 . . . . 11 . . . .
RIPLEY: COME ON!
MOTHER (voice over): 10 seconds . . . . 9 . . . . 8 . . . . 7 . . . . 6 . . . . 5 . . . .
She races to close the levers, the final step. . . . Too late
MOTHER (voice over): 4 . . . . 3 . . . . 2 . . . . 1 . . . . The option to override detonating procedure has now expired.
RIPLEY: Mother, I've turned the cooling unit back on! . . . Mother!
MOTHER (voice over): The ship will automatically destruct in T-minus five minutes.
Out of anger and frustration, Ripley smashes the control board.
RIPLEY: YOU BITCH!!!
INT. "B" LEVEL - COMPANIONWAY: She reaches companionway. Ripley staggers towards the air lock.
RIPLEY: You bitch. . . God damn it.
INT. "B" LEVEL - CORRIDOR LEADING TO NARCISSUS: The Narcissus berthed beyond. She sees the cat carrier.
Ripley picks up Jones. She drags Jones and raises the flamethrower. Turns to see if the Creature is behind her. Then advances down the passageway. Goaded on by the computer.
INT. NARCISSUS: Ripley scans the narrow deck...empty. She enters on the run. Hurls the cat box inside. Closes the shuttle hatch.
MOTHER (voice over): You now have one minute to abandon ship. The ship will automatically destruct in T-minus one minute.
EXT. NARCISSUS: She dives into the control chair. Flipping switches on a control board.
The retainer clips retract.
Ripley frantically straps herself in.
The shuttle is lowered to launch position.
INT. NARCISSUS: The shuttle launches. G-forces from the shuttles acceleration pulling against her. A blast of ram jets.
MOTHER (voice over): T-minus 30 seconds . . . . 29 . . . . 28 . . . . 27 . . . . 26 . . . . 25 . . . . 24 . . . . 23 . . . . 22 . . . . 21 . . . .
The Narcissus continues to power away from the mother ship. The larger bulk of the Nostromo quietly receding. All is strangely serene.
MOTHER (voice over): 20 seconds . . . . 19 . . . . 18 . . . . 17 . . . . 16 . . . . 15 . . . . 14 . . . . 13 . . . . 12 . . . . 11 . . . .
EXT. SPACE: The Nostromo drifts farther away from the shuttle-craft. Finally becomes a small point of light.
MOTHER (voice over): 10 seconds . . . . 9 . . . . 8 . . . . 7 . . . . 6 . . . . 5 . . . . 4 . . . . 3 . . . . 2 . . . . 1 . . . .
Like an atomic explosion, it transforms into expanding orange fireball. The shockwave hits the shuttle craft. Jolting and rattling everything within. Then all is quiet. The boiling fireball fades into nothingness. The Nostromo has ceased to exist.
RIPLEY (whispers): I got you.
Ripley unhooks herself from her straps. She removes Jones from the carrier and tucks him away in the sleep chamber.
RIPLEY: All right, it's nice to see you too. . . . Shhhh.
Ripley undresses to prepare for cryo sleep.
Ripley is adjusting various switches and controls.
Suddenly the lethal hand emerges from deep shadow. The Alien has been in the shuttle-craft all along. Ripley lets out a scream, then silencing herself.
The creature stirs.
