synopsis
Horror-film icon Christopher Lee guest stars in this Philip Levene-scripted Avengers episode. When British scientist Professor Stone (Lee), supposedly killed in an auto accident, suddenly shows up alive and healthy, Steed and Emma want to know why. Their curiosity is peaked when Stone subsequently survives 100,000 volts of electricity and an exploding artillery shell. The clues lead to a hush-hush government facility called the Neoteric Research Unit, whose director is that selfsame Professor Stone -- or is it merely his robotic duplicate? First broadcast in England on March 18, 1967, "Never, Never Say Die" was shown in America 13 days later.
