Orlando Natal is the best tenor in the world. Crowds of his fans besiege the stages of the Metropolitan Opera, La Scala, Covent Garden and other theaters. But of all his roles, Orlando prefers Werther... And one evening, in Mannheim, after another performance, he meets Carola K. From that moment on, opera and life strangely begin to resemble each other. Strange coincidences occur in Munich, Vienna and, finally, in Venice, when in the theater, to the sounds of an orchestra, Orlando almost repeats the tragic fate of his hero.
