80年代金球奖好剧。Jonathan Hart was a self-made millionaire--the CEO of Hart Industries, a global conglomerate. His gorgeous wife Jennifer was a freelance journalist. They were both amateur sleuths, and in every episode found themselves up to their eyeballs in murder, smuggling, theft and international espionage. They also managed to find time to snuggle together, as they loved each other very much. Max was their loyal, gravelly-voiced butler, cook & chauffeur, and Freeway their pet canine.
