Hawaii Five-O is an American police procedural drama series produced by CBS Productions and Leonard Freeman. Set in Hawaii, the show originally aired for 12 seasons from 1968 to 1980, and continues in reruns. Jack Lord portrayed Detective Lieutenant Steve McGarrett, the head of a special state police task force which was based on an actual unit that existed under martial law in the 1940s. The theme music composed by Morton Stevens became especially popular. Many episodes would end with McGarrett instructing his subordinate to "Book 'em, Danno!", sometimes specifying a charge such as "murder one".

While running from a drug deal gone bad, Mike Ross, a brilliant young college-dropout, slips into a job interview with one of New York City's best legal closers, Harvey Specter. Tired of cookie-cutter law school grads, Harvey takes a gamble by hiring Mike on the spot after he recognizes his raw talent and photographic memory.

Steve McGarrett returns home to Oahu, in order to find his father's killer. The governor offers him the chance to run his own task force (Five-0). Steve's team is joined by Chin Ho Kelly, Danny "Danno" Williams, and Kono Kalakaua.

A private investigator who works when he wants, lives in a beachfront estate in Hawaii, drives a posh Ferrari, runs up an unlimited tab at a swank bar, and charms attractive women in peril - that's the lifestyle of Thomas Magnum, aka Magnum, P.I.
