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.

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.
