Seven years later, Laure (now called Lily Watts) re-surfaces as the wife of the new American ambassador to France where a certain Nicolas Barto, a Spanish photographer, takes her picture which sets the stage for a motion of events as the evil Laure resorts to low, underhanded means to protect her former identity by emotionally and financially destroying Nicolas while evading her former partners-in-crime still looking for her to reclaim the stolen diamonds.
