Carla Behm is a long-time employee of a Parisian property development company; hardworking and well-informed, she's a 35-year-old secretary who'd like to move up the ranks, but her own timidity, caused largely by a serious hearing problem, always holds her back. Salvation comes in the form of Paul Angeli, the new trainee she manages to have hired. Paul is 25-years-old and completely unskilled--in fact, he's clueless. But he has other qualities: he's a thief, fresh out of jail and, what's more, he's handsome. As the saying goes, "it takes two to tango," and soon Carla and Paul begin a cagey dance for position and power--Carla learns to use Paul to channel her own aggression and ambitions, while Paul finds a way to make Carla a player in his own criminal plots and efforts at revenge. As both get to know each other better, their strange mutually dependent relationship ties them together in dark and fateful ways...
