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.
