In early-1930s Berlin during the Weimar Republic and the Nazis’ rise to power, the elegant Russian émigré and eccentric chocolatier, Hermann Hermann, leads a petite bourgeois life with his voluptuous and frivolous wife, Lydia. Troubled about his Jewish roots, Hermann convinces himself that he has seen his doppelgänger in the person of the unemployed vagabond, Felix, going as far as to hatch a murderous plan, intent on trading his very existence for an entirely new one. Now, Hermann’s desire for transcendence is gnawing at him. Will he get over the full-blown mental breakdown, and the profound despair?
