Film Synopsis

Hakim Gregory is a dangerous adventurer who specialises in selling secret documents to the highest bidder.  He has already destroyed one French spy network and is the French secret services' most wanted man.  His face totally changed by plastic surgery, Gregory goes into hiding.  When four agents are killed in Malaga, Spain, the security services are sure that Gregory is responsible and send their best man, Dan Layton, to investigate.  Disguised as a playboy, Layton is accompanied by Petula, a wealthy heiress who is in truth another secret agent.  It transpires that Gregory has taken refuge in a fashion house belonging to his mistress Dolores and bankrolled by a certain Misrah.  Layton feels that the time is right to catch Gregory, but he has not reckoned on the unwelcome arrival of his fiancée Marion, who is working as a tourist guide.  Unaware of Layton's real activities but jealous of the women with whom he has become mixed up, Marion is about to unleash a maelstrom of confusion in the world of espionage...
