Two female con artists prey on wealthy men in the French Riviera. The cunning and cultured Josephine (Hathaway) plots to swindle her targets from her ill-gotten luxury villa in the village of Beaumont-sur-Mer. The brash and free-wheeling Penny (Wilson) pursues the same scheme although it involves less refined circumstances and methods. Upon discovery of Penny's presence, Josephine wants to eject the interloper from her territory. The former, however, is stubborn and obnoxious so that, while they initially try to outfox each other, they decide to join forces to scam men who have wronged women. Josephine teaches Penny her craft believing she can polish her rough edges.
