A connoisseur of conning, Lawrence Jamison is running the ultimate royal scam on the Riviera: He´s posing as a deposed prince, raising funds for the freedom fighters of his stricken homeland. Should a wealthy commoner care to ´give her all´ to his noble cause, so be it - provided she also kicks in cash, jewelry and gambling chips. But his ´hustling highness´ gets royally flushed when one day a pretender to his throne turns up. He´s Freddy Benson, a small-time scam artist who has enough on Jamison to make a mess of the monarchy. So the rivals make a wager: the first to extract $50,000 from the next woman they see, wins. And the loser goes into exile. Enter Janet Colgate, a naive, American ´detergent heiress´. And the race is on.
