The series follows the adventures of Professor Darius Quanderhorn, a brilliant, but crazy, scientific genius who creates fantastic devices, and has assembled a team of assistants, including his part-insect "son", a recovering amnesiac, a brilliant scientist with a half-clockwork brain, and a captured Martian hostage. The year is 1952, but no one seems to have noticed that it has been that year for the past 65 years. In spite of Quanderhorn saving the world many times, the British government are tired of his eccentric behaviour, and have a mole in his team.
