Wagner moves to Lucerne, Switzerland with Cosima and her children. He is later joined by King Ludwig who wishes to abdicate in order to become Wagner's assistant. Wagner convinces him to return to Bavaria, where war with Prussia erupts. Hans von Bülow eventually also visits them in Lucerne, where Cosima asks him for a divorce, which he refuses. When Hans is overly tired by his work for Wagner, he leaves, and Wagner hires Hans Richter as his new assistant. They are visited by Friedrich Nietzsche. Cosima gives birth to Wagner's son.
