In search of the Doctor, an antimatter creature attacks UNIT and the Doctor is forced to send an SOS to his people, the Time Lords, but they have troubles of their own.

The fossilised hand is now in the possession of a technician called Driscoll at Nunton Power Station. He places the fossilised hand in the reactor core. The hand begins to draw power and reacts to the radiation, causing an overload situation. As the complex is evacuated, computers and equipment begin to blow up anjd Nunton's director, Professor Watson, is thrown to the floor.

Following the advice of the First Doctor, the Third Doctor and Jo have crossed through the black hole to the strange, desolate world of antimatter. The Second Doctor is left to figure out how to neutralize the dangerous anti-matter creature.

The Doctors are trapped in the universe of antimatter where they confront the creator of the world – Omega. A legendary figure from Time Lord history, Omega was long believed dead, but had actually been transported to the antimatter universe. It is clear that the exile has made Omega quite insane and it is now in possession of a terrible power.

Omega reveals his intention for the Doctors to take his place in eternal exile. But even he may no longer be able to escape…
