A crime drama that ran on {{ABC}} from 1972-1977, produced by Quinn Martin Productions (with [[Creator/WarnerBros Warner Bros. Television]] in season one). It starred Karl Malden as Det. Lt. Mike Stone, a veteran cop, and Creator/MichaelDouglas (in his StarMakingRole) as Inspector Steve Keller, Stone's younger partner. The series was shot on-location in UsefulNotes/SanFrancisco. Douglas left the show in its fifth and final season, and was replaced by Richard Hatch as Inspector Dan Robbins; this change was not popular with viewers (since ''[[Series/BattlestarGalacticaClassic Battlestar Galactica]]'' hadn't been created yet), so the series was cancelled.

Unique among crime shows since, the show's actors and writers took great pains to ensure an authentic portrayal of the San Francisco Police Department.


* TheButlerDidIt: [[spoiler: "Death and the Favored Few."]]
* CaliforniaDoubling: Usually averted, but the first scene in "Flags Of Terror" takes place in Tokyo, so...
* CrimeAndPunishmentSeries
* FramedFaceOpening: The TitleSequence has Detectives Stone and Keller over a blocky splotch design. Said design was also used for the guest cast montage.
* IncrediblyObviousBug: Seen in one episode. The tracking device is large and obvious (although not blinking or beeping), but it is planted on the back bumper of the car after the hero has gotten in, thus justifying them not noticing it.
* InSeriesNickname: Stone regularly calls Keller "buddy boy."
* InstrumentalThemeTune: Probably the funkiest outside of ''Series/BarneyMiller''.
* KilledOffForReal: [[spoiler: Steve in the ReunionShow]].
* NiceHat: Stone's ever-present fedora.
* PilotMovie: Based on the novel ''Poor, Poor Ophelia'' by Carolyn Weston.
* PoorlyDisguisedPilot: "Superstar," about a New York cop who comes to San Francisco to find his partner's killer and sticks around - in other words, ''{{McCloud}}'' in reverse - led into the short-lived {{Spinoff}} ''Bert D'Angelo Superstar'' (which actually began its network run two weeks ''before'' the episode aired).
* PutOnABus: At the start of season 5 Keller leaves the force to begin a teaching career.
* ReunionShow: 1992's ''Back to the Streets of San Francisco'', with Karl Malden and Darleen Carr (who played the recurring character of his daughter Jeannie on the original series). Michael Douglas doesn't appear, although [[Film/BasicInstinct he did play a San Francisco cop in another production that year]]. [[spoiler: The hunt for his murderer is a major plot element.]]
* SettingAsACharacter: Quinn Martin called the titular city "the third star of the series".
* ShownTheirWork: The authenticity of the portrayal of the SFPD.
* SocietyMarchesOn: There is an early episode where a critically wounded cop is rushed to the hospital and nothing is done for him en route beyond Carl Malden's character holding his hand sympathetically. As a result, with the widespread adaptation of paramedics that the contemporary series, ''Series/{{Emergency}}'', helped encourage, it looks criminally negligent to modern viewers to see an emergency patient being transported like that without being treated along the way.
* SuspiciouslySimilarSubstitute: Inspector Dan Robbins, Richard Hatch's character.
