Screenplay by TONY WILLIAMSON   Directed by CYRIL FRANKEL     The Champions investigate mysterious happenings on a tropical island which threaten world peace.     When secret agent Withers (BRANDON BRADY) is the third man to disappear while investigating a mysterious tropical island, Nemesis sends the Champions to find out what is happening. Craig (STUART DAMON) and Sharron (ALEXANDRA BASTEDO) pose as husband-and-wife castaways and are taken to the house of the island’s owner, Kellor (VLADEK SHEYBAL), while Richard (WILLIAM GAUNT) lands by parachute.   Richard discovers something very like a missile installation, but it is so securely guarded that he has to lie low. Meanwhile Craig and Sharron find themselves near-prisoners in Kellor’s house where Kellor himself seems to be under the influence of two Chinese, Kai Min (ANDY HO) and Tsi Chong (ROBERT LEE).   Richard makes another search of the installation and is captured by Kellor’s accomplice Perango (BENITO CARRUTHERS). Half-conscious, he is confronted by Craig and Sharron; Kellor wants to see if he recognises them. But, with their telepathic powers, they are able to warn Richard, who is then locked into a hut with several other prisoners, among them Withers. They have been forced to act as slave labour on the island.   Exchanging evidence, Richard and Withers realise that the missiles are intended to breach the Russian and American early-warning systems, thus making both countries think they have been attacked—and thus to start a third World War.   With the help of Richard’s super strength, they break their chains and escape from the prison into the jungle. Sharron and Craig also manage to flee from Kellor’s house, but they are captured and taken back, only to find that Kai Min has already set the missile into operation. American radar screens are already showing waves of enemy missiles approaching. On the aircraft carrier that is standing by to evacuate the Champions, even the Admiral (ALAN GIFFORD) is agitated.   However, Richard and his party of escaped prisoners are still free and when they attack the missile headquarters and overcome the guards, they have got to “persuade” Tsi Chong to find the button which will destroy the missiles...     AN PRODUCTION   Series created by Monty Berman and Dennis Spooner   © Copyright Incorporated Television Co.
