On deck of a ship from New York to Europe is Gustav Mahler. He is famous, the greatest musician in the world, but his body aches, has always ached. While the cabin boy gently but firmly looks after him, he thinks about the last years, the summers in the mountains, the death of his daughter Maria, whom he sometimes thinks he can still see, and of Anna, the other daughter, who is below deck, having breakfast right now. And he thinks of Alma, the love of his life, who drives him crazy and whom he has already lost. It is his last journey.
