Premise: Maxwell Smart, a.k.a. Agent 86, works for CONTROL, a Washington, D.C.-based counterintelligence agency. Totally inept as a secret agent, Smart can barely use the gadgetry the agency provides him (including a phone embedded in his shoe). Nevertheless, he and his fellow agents always seem to thwart the operations of KAOS, an organized crime outfit dedicated to evil. Agent 99 is Smart's smarter partner, a resourceful agent who eventually marries her bumbling cohort. Smart and Agent 99's boss is a man known only as The Chief.
