Bob Mitchell (Robert Cummings), an American playboy who recently arrived in Hong Kong, finds himself the recipient of a strange written message delivered by Inspector Chiao of the local police (Roy Chiao).
The note was taken from the lifeless body of another American man who had been murdered. The dead man had met Bob briefly a week before, but his next rendezvous with him was not allowed to take place.
The message simply reads: “Five Golden Dragons”.
With no knowledge of the dragons, Bob shrugs off any significance the note may have, although he does befriend two sisters, Margret (Maria Perschy) and Ingrid (Maria Rohm), only to discover that Margret has worked for the mysterious dragons.
Her association with Bob seals her fate, and now – being no longer of any use to this secret organisation – she is disposed of in no uncertain manner, leaving Bob as the number one suspect for the crime.
He escapes arrest and visits the Happy World nightclub, where his suspicions about certain employees there become surprisingly factual.
He is further drawn into the web of secrecy by Magda (Margaret Lee), a cabaret singer who – it is later discovered – is operating with three others, posing as the mouthpiece of the fifth executive member of an international smuggling ring – the Five Golden Dragons.
The five members (whose identities have remained a secret, even to each other, throughout their years of crime) are key men in the world’s capitals, and they operate a huge illicit traffic in gold.
They are to meet each other for the first time in Hong Kong to finalise terms for a sell-out to the Mafia, who are moving in to take over their organisation for fifty million dollars.
Magda, Peterson, the club’s manager (Sieghardt Rupp) and Gert (Klaus Kinski), a cool and deadly assassin, are eager to find a man to represent them at his historic meeting – a man to take all the risks and ensure that their cut of the $50 million is obtained without complication.
Magda decides that Bob is their man, and his assistance is secured when he learns that they are holding Margret’s sister, Ingrid, as hostage. If, however, it is disclosed that he is an intruder, death would be his reward.
Klaus Kinski’s voice was dubbed by Robert Rietty, and Domino provided Margaret Lee’s singing voice.
