"Inferno" is the twenty-eighth instalment of Gerry Anderson's Captain Scarlet And The Mysterons, and one in which the Mysterons are effective. In it, the Mysterons employ a likeness of the SKR4, a spacecraft-recovery vehicle, to destroy the Najama De-Salinisation Complex in the foothills of the Andes Mountains. Everything Spectrum does to protect the complex still ends up not being enough; indeed, the Mysterons are actually effective in spite and indeed BECAUSE of what Spectrum does.
