Bumbling Inspector Gadget battles the forces of M.A.D. with the aid of the various gadgets he has on his person: pop-up rollerskates, extensible arms, a helicopter-hat, etc. Despite the arsenal at his disposal (which is just as likely to misfire as work properly), Gadget never seems to be able to catch Dr. Claw, the mastermind behind M.A.D. Quite often, in fact, any success that Gadget might have is often caused by his niece Penny and her dog, who Gadget consistently fails to recognize as working incognito on the case.

This set is the complete Inspector Gadget series with all 30 episodes on 4 discs.
