Don't mention the war

Theo speaks in Berlin with Rudolph Herzog, who researched humor in the Third Reich. He discovered remarkable things. Theo also speaks with the half German-half Dutch Sven Ratzke about the disappeared art of Das Kabarett. And he is present at the Deutsche Tag der Wiedervereinigung, the day on which it is celebrated that the Wall fell and Germany became one country again, but they do not seem to be that united.
