When a legendary British Intelligence (SIS) agent is murdered, fellow agent Miss Maxwell (Lois Maxwell) is sent to find the late spy's girlfriend, Miss Yashuko (Yashuko Yama), who is unwittingly in possession of valuable information. Maxwell discovers that Yashuko is in the care of Dr. Neil Connery, a cosmetic surgeon who uses hypnotism in his practice. Yashuko is kidnapped from a medical conference in Monte Carlo by Maya Rafis (Daniela Bianchi), as part of a plot by Mr. Thayer (Adolfo Celi), code name Beta, of the terrorist organization THANATOS. The Secret Service's Commander Cunningham (Bernard Lee) assigns Connery to find Miss Yashuko.
Connery hypnotizes a beautiful girl named Mildred (Agata Flori) to acquire information and discovers that Miss Yashuko is located in a Spanish castle belonging to Lotte Krayendorf (Anne-Marie Noé). Connery rescues Miss Yashuko and obtains critical intelligence. This information leads to the discovery of THANATOS's plan to build a super magnet, powerful enough to turn off all mechanical products from New York to Moscow. The weapon is being assembled in a Moroccan rug factory, where all the employees are blind. Miss Yashuko is murdered by Mildred before revealing any further information. Mildred is then killed by Juan (Franco Giacobini), Connery's aide.
After arriving in Morocco, Connery is invited by Maya Rafis to a party held by Mr. Thayer. During the reception, Connery discovers that Mr. Thayer is planning to assassinate the head of THANATOS, known as Alpha (Anthony Dawson). Connery warns Maya about his discovery as she leads him to the rug factory. Upon entering the factory, Connery realizes that it is actually producing strands of uranium; the employees' blindness prevents them from discovering their dangerous role. Together, Connery and Maya track the uranium shipment to Switzerland, where Mr. Thayer, having failed to assassinate Alpha, has been driving the development of the powerful magnet. Together, with the help of a team of Scottish archers (as firearms are rendered inoperative by the magnet), Connery and Maya almost completely destroy THANATOS. After the completion of the mission, Commander Cunningham comments to Connery, "O.K. Connery! You were almost better than your brother."
Neil Connery was working as a plasterer in Scotland until he was sacked for losing his tools. Based on Neil's relation to his brother Sean, the matter received international media attention. When Terence Young heard Neil interviewed with his trade union about the matter on the radio he mentioned to Italian producer Dario Sabatello that Neil sounded like his brother Sean. Sabatello met Neil at the Caledonian Hotel in Edinburgh to recruit him to play the lead role in a Eurospy film. Neil recalled when he did his screentest the crew kept saying "OK, Connery, OK" that became the title for the film.
Experienced director Alberto De Martino who had previously filmed Upperseven, the Man to Kill and Special Mission Lady Chaplin (both 1966) recalled his father Romolo de Martino doing Neil's extensive makeup and problems with Neil's inexperience as an actor. He also recalled Sabatello approaching Sean Connery do to an appearance in the film that Connery emphatically refused.
Neil Connery’s voice is dubbed by an actor with an American accent. In an interview in Cinema Retro, Neil said that he was undergoing medical treatment when voice dubbing of the film was in progress, leading another person to voice his lines in the English version.
Lois Maxwell recalled she earned more money for the film that her combined award wage payments from all her appearances in the Eon Productions 007 films put together.

In contemporary reviews, Bosley Crowther writing for The New York Times referred to the film as "a wobbly carbon copy of the James Bond thrillers" Variety described the film as so "unbelievably inept", that "many viewers may find it hilarious fun." The Monthly Film Bulletin stated that O.K. Connery was a "grotesque parody of a parody" noting endless allusions to Neil Connery's brother Sean Connery. The review concluded that "the film as a whole is bad enough to be hysterically funny." The Cleveland Press referred to the film as a "dreary and dismal espionage movie" stating that the film lacked the "flair and skill with which the Bond films are made. The script is labored, the direction slow and the acting is barely adequate."
In Phil Hardy's book Science Fiction (1984), a review noted that "though it's stylishly mounted, the result is a routine Italian spy romp."
In an interview in 1996, Lois Maxwell said that Sean Connery, when he learned that she would join the cast, got very angry and started screaming: "You have betrayed me!" and he forgave her when she saved Neil from a fool at the press conference.
