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.
A 1960s action-adventure show with relatively calm pacing typical of that era, though the spy storylines and occasional action sequences prevent it from being as gentle as shows specifically designed for very young children.
