Inspector Gadget is a clueless trenchcoat-wearing, super-cop equipped with a seemingly endless array of contraptions and devices which are usually intergrated into his own body (for instance, telescopic limbs). His neverending mission is to thwart the world domination plans of Dr. Claw and his sinister worldwide organisation M.A.D. He gets his assignments from the long suffering Chief Quimby, who is always disguised as a potplant or hiding in an oven or somesuch, and who Gadget inevitably manages to unwittingly blow up in each episode. Though the Inspector always saves the day and comes away with the credit, the real crime-fighting action comes from his niece Penny, equipped with her 'computer book', and dog Brain, a master of disguise. Between them they manage to save Gadget from himself and solve the case, behind the scenes.
