It is the day that Antoine, a Paris advertising man, is to marry the lovely Gisèle and his best man Julien, a divorced statistician, tries to talk him out of it with tales of the hard times he had from women, ending in entrapment by his stunning secretary Denise, a professional virgin. Going into a bistro for a quick drink before they drive to the wedding, the owner Fernand, a retired villain and pimp, tells the two of his exploits that ended in marriage to pretty but pushy Sophie. Antoine decides to run for it, taking one of the tickets for the honeymoon in Greece and giving the other to Fernand. On board ship, he falls for the delectable Sandra, a professional confidence woman, who cleans him out of his money but eventually agrees to marry him. Fernand comes back with an old millionairess, former brothel owner, who drives a Rolls-Royce. At the wedding of Antoine and Sandra, Julien falls for a sweet brunette.
