Joe 90 is a 1960s British science-fiction television series following the adventures of a nine-year-old child, Joe McClaine, who starts a double life as a schoolboy-turned-spy when his scientist father invents a device capable of duplicating and transferring expert knowledge and experience from one human brain to another. Equipped with the skills of the foremost academic and military minds, Joe is recruited by the World Intelligence Network and, becoming its "Most Special Agent", pursues the ideal of world peace and saving human life.
