Original series (1966–1973)

Season 1 (1966–1967)

Series #	Episode #	Title	Directed by	Written by	Original Airdate	Production #
1	1	"Pilot"	Bernard L. Kowalski	Bruce Geller	September 17, 1966 (1966-09-17)	1
The Impossible Missions Force (IMF) must retrieve two nuclear warheads being kept in a hotel vault by a Caribbean dictator. Martin Landau "guest stars" as both IMF agent Rollin Hand and the dictator. The "hotel" exterior is the Los Angeles Griffith Park Observatory. This episode is notable as the mission instructions voiced by Bob Johnson are delivered via a vinyl LP instead of a tape. It is also the only episode written by series creator Bruce Geller.
2	2	"Memory"	Charles R. Rondeau	Robert Lewin	September 24, 1966 (1966-09-24)	3
An IMF agent with photographic memory allows himself to be captured to help discredit a politically connected mass murderer. This is the only "regular-format" episode in which the IMF does not receive its instructions via a recording - Briggs receives printed instructions on a card instead - and as such is the only "regular-format" episode in which Bob Johnson's voice is not heard.
3	3	"Operation Rogosh"	Leonard J. Horn	Jerome Ross	October 1, 1966 (1966-10-01)	4
When an Eastern European agent (Fritz Weaver) plans a biological attack on Los Angeles, the IMF must trick him into revealing the type and location of his devices. They convince him that it is three years into the future, that he is back in his own country, and that he is on trial for being an American spy. This is the first episode not to use the opening "apartment" sequence.
4	4	"Old Man Out (Part 1)"	Charles R. Rondeau	Ellis Marcus	October 8, 1966 (1966-10-08)	2
While the rest of the IMF team pose as a traveling circus, Rollin Hand gets himself put into an "inescapable" prison to try to rescue an elderly dissident scheduled to be executed within days, Catholic Cardinal Anton Vossek. Vosseck is overtly based upon József Mindszenty, and his high-profile imprisonment by a totalitarian government in the Eastern Bloc.
5	5	"Old Man Out (Part 2)"	Charles R. Rondeau	Ellis Marcus	October 15, 1966 (1966-10-15)	2
The plan hits a snag when Cardinal Vossek is transferred to another cell.
6	6	"Odds on Evil"	Charles R. Rondeau	William Read Woodfield and Allan Balter	October 22, 1966 (1966-10-22)	5
The autocratic prince (Nehemiah Persoff) of a small principality with a casino must be bankrupted before he can use his funds to buy weapons to attack a neighboring state. To accomplish this, the team uses a computer to predict the winning number in a roulette wheel (winning number displayed on a wristwatch), while also rigging a game of baccarat through the use of marked cards which can be seen with special contact lenses. This episode shares many similarities with Ian Fleming's Casino Royale.
7	7	"Wheels"	Tom Gries	Laurence Heath	October 29, 1966 (1966-10-29)	8
The IMF must "un-rig" an election to prevent a corrupt government from taking power. This episode guest stars Mark Lenard of Star Trek fame as an unscrupulous bureaucrat.
8	8	"The Ransom"	Harry Harris	William Read Woodfield and Allan Balter	November 5, 1966 (1966-11-05)	9
When a friend's daughter is kidnapped by a crime lord, Briggs calls in his IMF team to rescue her. This is the first of several episodes in which the IM Force conduct "off-book" missions, and the only one that Dan Briggs led. It is also the first instance of the IMF taking on domestic organized crime.
9	9	"A Spool There Was"	Bernard L. Kowalski	Ellis Marcus	November 12, 1966 (1966-11-12)	6
Rollin and Cinnamon pose as reunited ex-lovers in an unfriendly country to retrieve a spool of recording wire hidden by a dead agent.
10	10	"The Carriers"	Sherman Marks	William Read Woodfield and Allan Balter	November 19, 1966 (1966-11-19)	13
The IMF infiltrates an artificial American town located behind the Iron Curtain where enemy agents are trained to act and think like Americans for an unknown mission. The concept of a simulated American town being used to train agents had previously been used in the Danger Man episode "Colony Three" and would later be used in the Alias episode "Welcome to Liberty Village". This episode also shares many similarities with Ian Fleming's novel On Her Majesty's Secret Service. Guest stars George Takei.
11	11	"Zubrovnik's Ghost"	Leonard J. Horn	Robert Lewin	November 26, 1966 (1966-11-26)	11
In this "haunted house" episode, Rollin, Barney, and Ariana Domi (Martine Bartlett) pose as investigators of the supernatural to find out why a scientist believes the ghost of her dead husband is telling her to go behind the Iron Curtain. The opening tape sequence utilizes the same location as the germ laboratory in the previous episode, "The Carriers".
12	12	"Fakeout"	Bernard L. Kowalski	Leigh Chapman	December 3, 1966 (1966-12-03)	7
Cinnamon romances the ill-mannered leader of an international narcotics syndicate (Lloyd Bridges) to fool him into crossing the border into a country where American authorities can finally arrest him.
13	13	"Elena"	Marc Daniels	Ellis Marcus	December 10, 1966 (1966-12-10)	10
In a South American country, a female IMF agent named Elena (Barbara Luna) begins exhibiting paranoid behavior, and Rollin is assigned to find out why before she is assassinated as a precaution. The same laboratory set (and hallway with the elevator) in "The Carriers" is shown in this episode; also, an accident inside the laboratory occurs in both episodes.
14	14	"The Short Tail Spy"	Leonard J. Horn	Julian Barry	December 17, 1966 (1966-12-17)	14
Briggs, Cinnamon, and Barney are tasked with protecting a Cold War scientist from two rival assassination bureaus determined to liquidate him before an important conference. When Cinnamon is assigned to seduce one of the assassins to prevent the killing, he claims that he wants to defect; Briggs becomes worried that she might be falling in love with her target.
15	15	"The Legacy"	Michael O'Herlihy	William Read Woodfield and Allan Balter	January 7, 1967 (1967-01-07)	15
In this "treasure hunt" episode, the sons of Adolf Hitler's most trusted Nazi officers gather in Zurich, Switzerland, to locate Hitler's "lost fortune." Rollin infiltrates the Neo-Nazi cell whose members plan to uncover and use the latter $300 million legacy to launch the Fourth Reich. This is one of four episodes to be remade for the 1988 revival ("sons" was changed to "grandsons"); the others are "The Condemned," "The System" and "The Killer." This is also the only episode of either incarnation in which the villain escapes at the end.
16	16	"The Reluctant Dragon"	Leonard J. Horn	Chester Krumholz	January 14, 1967 (1967-01-14)	16

18	18	"The Trial"	Lewis Allan	Laurence Heath	January 28, 1967 (1967-01-28)	12
Briggs poses as a would-be saboteur to orchestrate the downfall of an Eastern European secret police chief who plans to discredit the United States by convicting a US citizen of espionage at a show trial.

The character of Dan Briggs does not appear in the episode.
24	24	"The Train"	Ralph Senensky	William Read Woodfield and Allan Balter	March 18, 1967 (1967-03-18)	23
The IMF team must simulate a train ride carrying a dying prime minister to a Swiss hospital, to convince the leader that his chosen successor would become an oppressive dictator upon his ascension.

25	25	"Shock"	Lee H. Katzin	Laurence Heath	March 25, 1967 (1967-03-25)	24
When an American envoy is kidnapped and replaced by a disguised agent planning to assassinate a U.S. diplomat, the IMF must stop the assassination and elicit the whereabouts of the real envoy out of the enemy agent.
