Symphony : In 1827, Harriet Smithson, a beautiful and talented young Irish actress, makes an unusual decision - she joins an English company in the bold experiment of taking Shakespeare to Paris. With the ferment of revolution in the air, the new generation is longing for a new kind of passionate, spontaneous art. And to Harriet's astonishment, it is embodied in her - La Belle Irlandaise. In the midst of this frenzy she finds herself pursued by an intense young composer, Hector Berlioz. So begins a painful and profound love affair. She is his muse; his obsession; and Berlioz's Symphonie Fantastique, inspired by Harriet, will change music forever.
