Berlin, 1928, the dying days of the Weimar Republic shortly before Hitler and the Nazis came to power. It was a period of decadence and excess as Berliners - after the terrible slaughter of WWI and the hardships that followed - are enjoying their own version of Babylon. Bernie is a young detective working in Vice when he gets a summons from Bernard Weiss, Chief of Berlin's Criminal Police. He invites Bernie to join KIA - Criminal Inspection A - the supervisory body for all homicide investigation in Kripo.
