European Crown Princess Isabel is mistaken for the neglected first wife by Victoria, a gold digger brought back by her younger brother. The latter runs amok in Isabel's private manor and demands control of the estate, while Isabel watches coldly as she digs her own grave. After Isabel's true identity is revealed, Victoria's resentful assistant Anna sells royal secrets to Count Drach, Isabel's political rival, who seizes the opportunity to smear the Crown Princess. Isabel crushes the rumors with absolute power at the charity gala, wins the unanimous support of ambassadors from six countries, completely defeats her political foe, and also helps her younger brother Matthias grow and transform.
