Vila and Tarrant travel to the planet Pharos to collect Muller, a cybernetics specialist whose companion, Vena is waiting for him at Xenon base with the others. As they arrive, Scorpio receives an alarm, and when Tarrant teleports down he finds Muller, a dead guard, and a box that seems to disturb the scientist. They teleport back to the ship, but when Muller sees that Tarrant has brought the box, he goes berserk and attacks them. When Vila tries to stun him, Muller apparently dies. They place him in cryogenic suspension and return to Xenon base. Entering orbit, the ship’s systems fail; Orac advises a quarantine, but, unwilling to allow Tarrant and Vila to die, Avon teleports them down to the planet. Muller inexplicably appears on the base and kills Vena. The crew realise that it is not Muller, but an android, which has killed its creator and used his head as a disguise - the real head, an inhibitor, is in the box Tarrant found. The android demands Orac, planning to combine with it and then enslave humanity. Avon wants the android for his own purposes, and they lure it outside the base and knock it out by tricking it into crossing an electrified bridge. Avon installs the inhibitor head, but the shock knocks him out. While he is unconscious, Tarrant blows up the android, much to Avon’s later fury.
