The Mysterons threaten to destroy the Triumvirate of Europe, the three most powerful men on Earth after the World President.

Captain Scarlet and the rest of Spectrum are in a desperate race against time to defeat the Mysteron's latest threat, the total destruction of the massive desalination plant at Najama, high in the Andes Mountains.

Spectrum personnel inexplicably take leave of their senses, due to drinking some champagne drugged by the Mysterons, who have threaten to destroy the World Navy Complex at Atlantica.
