Siena Ricci is shrewd, seductive, and an expert in the art of deception. Masking her identity behind the guise of Marie Lacroix, a specialist in antiques and objets d'art, she swindles her employer's wealthy clients out of their valuable possessions. She hasn't yet met the man she can't manipulate, but then the con she's playing on Jonathan Woodward has only just begun. Jonathan proves to be an easy mark, but he's also enticingly irresistible. As their relationship heats up, her plot to steal his multi-million-dollar antique trinkets begins to unravel. Noticing a subtle change in Jonathan's demeanor, Marie questions whether she's still in control of the con or if she's blindly become the gullible victim of her own scheme.
