Wealthy native Brit Lawrence Jamieson (Michael Caine), living in Beaumont-sur-Mer on the French Riviera, earns most of his money through big cons on wealthy, unsuspecting women. With the help of his associates, corrupt Police Inspector Andre, who provides him most of his intel, and his butler Arthur, he pulls scams such as pretending to be a foreign deposed Prince who needs money to finance a secret war to liberate his people. Beaumont-sur-Mer, and thus his world, is invaded by brash American Freddy Benson (Steve Martin), another con man whose targets are also wealthy, unsuspecting women. Lawrence believes Freddy is "the Jackal," a con man whose true identity is unknown, but who is known to be working his way through Europe. While Lawrence pulls in thousands of dollars per scam, Freddy only takes in ten or twenty dollars, or if he is lucky, hundreds of dollars per victim. Lawrence's initial effort to push Freddy out of his territory proves unsuccessful when Freddy discovers from "Lady Fanny" that Lawrence is a con artist just like he is. Thus, Freddy decides to blackmail Lawrence in order to learn from him the art of the sophisticated, suave, 'gentleman' and thus acquire greater lucre. However, an unexpected 'element' changes the course of their endeavors.
