Françoise Legrand, better known as "Sappho", attractive young woman of the Parisian bourgeoisie, flits from man to man with the consent of Maurice Duran-Vior, his rich protector, a renowned financier. At a social gathering, she meets Lionel de Lancey, younger than she, a cool diplomat, and, as usual, she spends the night with him.

Inspector for a major insurance company, Clint de La Roche, known as "le vicomte", is enjoying a pleasant vacation on the Spanish coast with a few pretty girls and his assistant, Billette, when he is urgently called back to Paris to investigate a bank robbery. The bank manager has had the key to the security system stolen by a certain Tania. But Tania is killed in a car bomb attack. However, Clint soon discovers that behind this case lies a rivalry between the gangs of Rico Barone and Marco Demoygne, who are fighting for control of the drug market.
