The composer Richard Wagner and the philosopher Friedrich Nietzsche were good friends, but on the day of Richard Wagner's greatest triumph, the opening of his Opera in Bayreuth, Nietzsche walked away from the friendship and later threatened to kill Wagner. Shortly after these strange events, Wagner died and Nietzsche went completely mad. The details of the feud between these giants of 20th century culture are revealed when Richard Wagner's Ghost materializes in the delusional Nietzsche within the walls of Turin's Lunatic Asylum.
