Berlin, Spring of 1995. While a group of neo-Nazis are preparing an anniversary bash of disastrous proportions, an old physics professor returns to Potsdam to atone for his sins, an Italian postdoc designs an experiment that will determine the fate of the universe, and, in a room at Le Charit?, a Holocaust survivor tells his tale to the willing ear of a young psychologist. Who is that talking cat, why do ghosts of SS soldiers roam the city, and what is Speer's favorite actress up to?
