OPERATION KID BROTHER

Ward Jones lands his light aircraft at an airfield in Monte Carlo, but it is destroyed following a collision with a remote controlled car operated by Thayer, a member of the secret THANATOS organisation. Jones dies in the explosion, and a package is retrieved from the wrecked aircraft by Thayer's henchwoman Maya.

In a medical conference in Monte Carlo, Jones' girlfriend Yachuko escapes from Thayer's henchmen, aided by cosmetic surgeon Neil Connery. She is later kidnapped by British agent Miss Maxwell, but another of Thayer's henchwomen, Krayendorf, then captures Yachuko.

Connery meets Maxwell and her boss Commander Cunningham. Jones had wanted to sell them the package and asked them to protect Yachuko, who also had access to relevant information. Connery believes that Jones has transferred the data to Yachuko using hypnosis. Cunningham demands that Connery help retrieve the information. After being reminded that he killed one of Thayer's henchmen in a fight at the conference, Connery agrees to help in exchange for the police investigation being dropped.

Cunningham dispatches Connery to Malaga where Yachuko has been spotted. Connery and Maxwell are met by Juan, who has left his wedding early to greet them. Thayer's henchwoman Mildred has followed them to Malaga, but Connery hypnotizes her to reveal Yachuko's location, Krayendorf's castle.

Firing an arrow, Connery short-circuits the electric fence protecting the castle and destroys its defensive machine gun position. Connery, Maxwell, Juan and their colleagues then attack the castle and defeat Krayendorf's henchmen. Juan kills Krayendorf and Connery rescues Yachuko. Using hypnosis, he accesses most of the critical information, but Mildred kills Yachuko before the process is complete. Juan then kills Mildred.

Meanwhile, an "atomic nucleus" is being transported by American military police. Maya and more henchwomen dress up as can-can dancers, lure the MPs from their vehicles and steal the nucleus. With it, THANATOS can now power their "ultra-high-frequency magnetic waves", which will cause all metal machines to stop working. This will force world leaders to give THANATOS their gold.

Following up information revealed by Yachuko, Cunningham persuades Connery to travel to Tétouan, Morocco, where Thayer owns a rug factory staffed exclusively by blind men. Goons try to kill Connery in the street, but he is rescued by Maya. THANATOS leader Alpha wants Connery dead, but Thayer wants to keep him alive. Connery attends a party hosted by Thayer, who resents Alpha's power. He is plotting to replace Alpha with a double, and Connery is required to change the man's face. Thayer also plans to murder his henchwomen, a fact that Connery passes on to Maya.

Disguised as a blind Moroccan weaver, Connery infiltrates the factory, where the workers are in contact with dangerous radioactive materials. Connery warns a worker, who soon instigates a riot. Connery is eventually captured by Thayer. Later, at a yacht, Connery is to be forced to transform Thayer's henchman Kurt into an Alpha lookalike. Before the operation begins, Connery hypnotises Kurt, causing him to attack Thayer. Meanwhile, the female crewmembers of Thayer's yacht attack their male counterparts. The women take over the yacht, but Thayer escapes in a rubber dinghy.

Alpha blames Thayer for his failure and demands that he kill himself. Thayer kills Alpha instead and takes control of THANATOS. Connery and Maya meet Juan in Munich, where they are also joined by the Scottish members of a Monte Carlo archery club.

Using a Geiger counter to detect the radioactive rugs, Connery and Maya locate THANATOS's secret lair. Meanwhile, Thayer triggers the magnetic wave, paralysing machinery all over the world. Guns are no longer operational, so bows and arrows are now optimal weapons. Connery, Maya, Juan and the archers enter the base.

While the archers tackle Thayer's henchmen, Connery plants an "anti-magnetic explosive" to stop the wave. He is discovered by Thayer and they fight, culminating in an archery duel in which Thayer is killed. Connery, Maya and the surviving archers escape from the base, which explodes. Cunningham wants to recruit Connery as a permanent agent, but Connery uses his hypnotic powers to dissuade him. Maya and Connery depart on Thayer's yacht for a romantic cruise.

Connery and his allies thwart THANATOS's world domination plan, dismantling the syndicate's plot involving the atomic nucleus and magnetic weapon.

The ending sees the civilian protagonist leveraging unconventional skills to dismantle a high-tech criminal conspiracy, subverting the classic spy formula. Instead of relying on brute force, Connery’s medical talents and psychological savvy tip the scales, highlighting the film’s parody of the Eurospy genre and its gentle mockery of spy cinema conventions.
