The CBS television network produced Hawaii Five-O, which aired from September 20, 1968, to April 5, 1980. The program continues to be broadcast in syndication worldwide. Created by Leonard Freeman, Hawaii Five-O was shot on location in Honolulu, Hawaiʻi, and throughout the island of Oʻahu and elsewhere in the Hawaiian Islands with occasional filming in locales such as Los Angeles, Singapore, and Hong Kong.
The show centers on an elite fictional state police unit led by former U.S. Naval officer Steve McGarrett (played by Jack Lord), a detective captain, appointed by the Governor, Paul Jameson. In the show, McGarrett oversees state police officers — the young Danny "Danno" Williams, veteran Chin Ho Kelly (Kam Fong Chun), and streetwise Kono Kalakaua for seasons one through four. Honolulu Police Department Officer Duke Lukela joined the team as a regular, as did Ben Kokua, who replaced Kono beginning with season five. Occasionally, McGarrett's Five-O team is assisted by other officers as needed: Det. Frank Kamana (Douglas Mossman), P.O. Sandi Wells (Amanda McBroom), medical examiner Doc Bergman (Al Eben), forensic specialist Che Fong (Harry Endo), and a secretary.
The title of the show refers to Hawaiʻi's status as the fiftieth U.S. state. At the time of the show's premiere, Hawaiʻi had been a state for nine years. The Five-O team consists of three to five members (small for a real state police unit), and is depicted as occupying a suite of offices at the ʻIolani Palace. Five-O lacks its own radio network, necessitating frequent requests by McGarrett to the Honolulu Police Department dispatchers.
For 12 seasons, McGarrett and his team pursued international secret agents, criminals, and organized crime syndicates plaguing the Hawaiian Islands. With the aid of District Attorney and later Hawaii Attorney General John Manicote, McGarrett is successful in sending most of his enemies to prison. One such crime syndicate, introduced in the fifth season, was led by the Vashon family, portrayed by Luther Adler and Harold Gould. Other criminals and organized crime bosses on the islands were played by actors such as Ross Martin, Gavin MacLeod, and Ricardo Montalbán.
By the 12th and final season, series regular James MacArthur had left the show (in 1996, he admitted that he had become tired of the role and wanted to do other things), as had Kam Fong. Unlike other characters before him, Fong's character, Chin Ho Kelly, at Fong's request, was killed off, murdered while working undercover to expose a protection ring in Chinatown in the last episode of season 10. New characters Jim "Kimo" Carew (William Smith), Lori Wilson (Sharon Farrell), and Truck (Moe Keale) were introduced in season 12 alongside returning regular character Duke Lukela.
