Three agents of an international security organisation are granted miraculous powers of physique and mental ability when rescued after an air crash in Tibet. They become super humans.
Craig Stirling (STUART DAMON) and Richard Barrett (WILLIAM GAUNT), both agents of the international security organisation known by the code name of Nemesis, and Sharron Macready (ALEXANDRA BASTEDO), a trained bacteriologist with the organisation, are detected after raiding a secret germ warfare establishment. They get away with a test tube containing the incriminating germs, but their plane is so badly damaged that they crash in the desolate mountain regions of Tibet. All three are seriously injured: death seems inevitable.
Back at Nemesis, the organisations head, Tremayne (ANTHONY NICHOLLS), waits for news and tries to pacify two impatient Military Attaches (KENNETH J. WARREN and JOSEPH FURST), who are convinced that the three operators must be dead. Tremayne urges them to wait a little longer
The three agents return to consciousness to find themselves miraculously unhurt. Their wounds are healed, but marked with gold scars. Only Craig has a vague, dream-like recollection of being operated on by a very old man. He and Sharron decide to trek towards India, but Richard says he must find their unknown rescuers, his decision strengthened by Sharrons belief that she saw some kind of city below them just before they crashed.
They set off in opposite directions, and Richard finds the secret city and meets its aged but ageless Elder (FELIX AYLMER) who admits to having cured them, and also tells him that he and his companions have now been endowed with super-human qualities. Although they are still human and not immortal, they are champions in every field of endeavour, with sharpened mental capacities. Only experience will teach them how to use these improved bodies and minds. But, in return, they must not reveal the existence of the secret city.
One of their new powers is a telepathic understanding. They can hear each other over long distances. They will also be aware when the others are in danger. And at that very moment, Craig and Sharron are in danger: they have been captured by the pursuing Chinese.
Richard follows them and finds Craig, who has been shot and left for dead. Miraculously, he has again survived. The two men now have to rescue Sharron. Their new powers are put to their first test
