The show stars Robert Wagner and Stefanie Powers as Jonathan and Jennifer Hart, a wealthy couple who lead a glamorous jetset lifestyle. The Harts often find themselves involved in cases of smuggling, theft, corporate espionage and, most commonly, murder. The series ended after five seasons on May 22, 1984, but was followed by eight made-for-television movies, from 1993 to 1996.
The premise of the show is summed up in the opening credits sequence, narrated by Max, the Harts' majordomo (Lionel Stander), as he introduces the characters. Jonathan Hart (Robert Wagner) is the CEO of Hart Industries, a global conglomerate based in Los Angeles. His wife Jennifer (Stefanie Powers) is a freelance journalist. The Harts often find themselves involved in cases of smuggling, theft, corporate and international espionage and, most commonly, murder.
