It is the second half of the 19th century in France. Paris’ Opera House is the stage where singers from all over Europe dream to be. However, there is a fearful rumour in the air, which seems to regard a mysterious man within the Opera House. Christine is a young opera singer who has lost all passion for singing. Her efforts to become the ’prima donna’ - the top opera singer of the house - just aren’t enough…until one day, a beautiful voice speaks to her; a voice from whom she starts receiving singing lessons. ‘I won’t hand you to anybody…’ And so, Christine is pulled into a spiral of love, lust and hate between five men in Paris’ Opera House; a place where secrets have yet to unfold.
