Le chacal traque les filles(1967)

François Merlin, nicknamed "The Jackal", returns to France after many years in America. He meets up with his sister Mishka, who makes her living from an antiques business. François has a highly developed seduction technique, and his victims unsuspectingly carry out the foreign missions he sends them on, from which they never return. Ranko, the Parisian kingpin of this kind of business, can't bear to see himself competing, and a fight to the death begins between the two crooks.
