At a corporation's base on the Neptune moon Triton (moon), mercenaries are setting up a defense perimeter to try to hold off an unstoppable cyborg warrior. The commander Saggs and scientist Nabel seal themselves inside the control room. The cyborg destroys the soldiers' tank and then attacks a helicopter, which crashes into the control room. The soldiers are killed one by one, until Nabel finally deactivates the cyborg with a remote control. The remaining corporate employees discover that the cyborg was created by Nabel for company owner E.J. Saggs. Saggs takes the remote from Nabel. He reactivates the cyborg and orders it to kill Nabel.
