Charlotte is searching for Hitler's medical records from 1918. Goebbels stages the funeral of an SA member as a state ceremony against "red murderers." Göring orders mass arrests. The SA infiltrates the police force. Chief Inspector Böhm makes a discovery that Charlotte absolutely must know about. While the political division is being infiltrated by the Nazis, Böhm and Charlotte continue their investigation in secret.

Gereon wakes up, severely beaten, in a Berlin SA prison next to the journalist Heymann. Anyone who opposes the movement at the castle has to deal with State Councilor Wendt. Resistance is now only possible if it's well disguised. Ms. Behnke prepares for this role. Another former patient from Dr. Forster's days at the military hospital is dead. Böhm suspects a series of murders, but Wendt sidelines him.
