State police force led by former U.S. naval officer Steve McGarrett is appointed by the Governor, Paul Jameson. McGarrett oversees State Police officers—a young officer, Danny Williams, Chin Ho Kelly, and Kono Kalakaua.Occasionally, McGarrett's Five-O team is assisted by other officers as needed: medical examiner Doc Bergman, forensic specialist Che Fong, and a secretary.
McGarrett and his team hound international secret agents, criminals, and organized crime syndicates plaguing the Hawaiian Islands. With the aid of District Attorney and later Hawaii's Attorney General John Manicote (played by Glenn Cannon), McGarrett was successful in sending most of his enemies to prison.
