The end of a British-held contract over the oil fields in the fictional land of Ramat sets the stage for a tense political game. With the current ruler eager to sell those rights to the Eastern Bloc, the British fear a dangerous shift in power—unless the heir, Prince Jamil, who is coming of age at fourteen, can be kept on a pro-British path. To safeguard the oil and the Anglo Oil Media Company, the government, led by Sir Robert, initiates a quiet, high-stakes plan: kidnap the prince with his own consent so he remains protected from any assassination plot before he fully ascends to power. John Le Mesurier.
A man on the inside, Colonel Drexel, is enlisted to shepherd the mission, and he leans on his old ally from wartime days, David Frazer, to make the operation plausible and discreet. Frazer, a seasoned operative with a knack for getting in and out of tight spots, is promised a handsome reward—£500 for the work. He agrees and heads to Spain, where a safe house will shelter the prince as the extraction unfolds. The arrangement hinges on trust, timing, and the ability to outpace a web of possible traitors.
In the sunlit lanes of Spain, Frazer’s path quickly crosses with Sophie, a striking Frenchwoman who offers him a ride to his villa. The encounter isn’t merely a social flirtation; Sophie and her circle radiate a ring of danger, and Frazer soon senses that the boat, the boat house, and the people who drift around them may be connected to smugglers or some other shadier enterprise. Frazer’s suspicions are sharpened by the presence of a large, quiet man who keeps a watchful eye on the proceedings. As Frazer navigates this foreign terrain, the gears of the kidnapping plan start to turn more quickly, with the original objective—the prince’s safe transfer—taking moments of priority over the surface romance building between Frazer and Sophie.
Meanwhile, Drexel succeeds in spirit, guiding the prince out of Ramat and back toward a villa in Spain where the operation will be staged. The next day, Sophie attempts to breach the villa’s boat house, only to have Frazer stand in her way. He also keeps Lady Dunwoody, an English tourist named Leslie Dunwoody, from lingering outside the house, providing a calm but firm shield against prying eyes. Sophie’s shadowy entrance later that day touches Frazer directly: she longs for him, even as she steps back into the shadows and morphs into a more complicated partner in these dangerous games. As Frazer wrestles with the situation, the gang makes their own move toward the boat, and a confrontation seems imminent.
The tension spikes when Frazer takes the boat out to investigate the gang’s activities, hoping to run into Sophie again. But a knock at the dock from behind sends him sprawling into darkness, and when he comes to, the prince is missing. Benson, the stern security chief, suspects treachery and tries to haul Frazer in for questioning, but the gang abducts Frazer first, shipping him away in a wine barrel that somehow half-drunk his senses. The intoxicated Frazer is forced to watch as Sophie reappears and, to his horror, the two realize they are being used as a bargaining chip in a larger snare.
The gang’s ringleader uses the setup to frame Frazer as the kidnapper, including the moment that Frazer is seen kissing Sophie in some intoxicated reverie. He’s furious with Sophie for the deception, but her help proves indispensable when he discovers the real betrayer—Drexel himself. Drexel’s plan isn’t to kidnap for a simple ransom; he wants to cut Frazer out and claim a much larger payoff from the oil company by controlling the prince’s fate. The two former allies confront one another, and Frazer’s resolve hardens as he fights back in a decisive clash that ends in a narrow victory, interrupted only by the return of Leslie Dunwoody, who reveals a startling motive of his own: he’s a private detective hired by his wife to uncover Drexel’s treachery.
What follows is a twist-filled interlude in which Dunwoody isn’t the ally he appears to be. He’s working for the current ruler of Ramat, and his aim is to destroy the prince’s life to secure a different political outcome. Frazer and Sophie are captured in a circus cage during this coup, and the prince is paraded as the key to a new political deal. In the circus arena, the knife-thrower, the little person, and the performing dog all contribute to a theatrical backdrop for the shifting alliances. Drexel arrives, pulling the threads of the plot toward a dangerous denouement, where Dunwoody’s attempts to kill the prince are thwarted, and Drexel’s arrival effectively halts the dangerous private detective’s plans.
The chase resumes with Drexel seizing the prince and attempting to cross a dam construction site, with the image of a child’s safety in the balance. Dunwoody's earlier double-cross is starkly underscored as the prince speaks up, recognizing that Drexel is the real instigator behind this kidnapping. A brutal gunfight erupts, and the dam’s bridge collapses in a tense moment of peril. Frazer acts with nerve and quick thinking, saving both the prince and Drexel from certain peril. Yet Drexel remains ruthless and continues to press his own advantage, even as the arriving authorities—led by Benson and the police—move decisively to end the crisis.
Back in Sir Robert’s office, the operation is deemed a success in its own way. The group breathes a collective sigh of relief, even as the fallout becomes clear. Benson clarifies that Dunwoody was the mastermind of the double kidnapping, a revelation that reframes what the group thought they understood about the mission. Drexel, meanwhile, basks in the dubious comfort of a new job with the oil company, boasting that the compensation is substantial enough to salve any conscience. Sir Robert’s pragmatic practicality is the final note of the evening: Frazer’s £500 fee has to be reduced by the day’s tax complexity, and the cold arithmetic reveals that he’ll actually walk away with a mere £11—the kind of calculation that lingers long after the glittering veneer of the operation fades.
In the end, the film’s tension lies not in a single spectacular result but in the uneasy balance of power, loyalty, and profit. The British and the oil interests come away with a controlled victory, the prince remains protected, and the men who navigated this perilous covert landscape must live with the consequences of their choices. The story closes on a mix of relief and rueful humor, as Frazer recognizes the odd, almost accidental nature of his reward, while the larger geopolitical chessboard remains as risky as ever.
