It is revealed that Gereon managed to revive Charlotte. Henning and Czerwinski pick up Gereon and board the train. Bruno and the Black Reichswehr halt the train but are ambushed by the Armenian's gang. Gereon confronts Bruno on the train and discovers that the gold is actually fake. Henning and Czerwinski incapacitate the Armenian gang with anaesthetic gas while Bruno starts the train. After fighting with Gereon on top of the train, Bruno is killed after causing a gas explosion. Wendt becomes the new Head of the Political Police and wants Gereon to unofficially lead a new covert Internal Review department that investigates internal political crimes and corruption. Charlotte becomes a deputy homicide detective. Observing the Sorokin painting in Svetlana's apartment, Gereon and Charlotte deduce that Svetlana is an imposter and that the round container of the freight train car, not its content (which was fake gold), was made of pure gold. In Paris, Kardakov watches Svetlana sing in a cabaret. Gereon is attacked by a KPD group led by Dr. Volcker but is rescued by the Armenian and taken to Dr. Schmidt. Under hypnosis, Gereon realises the truth: that he did not attempt to rescue his brother Anno, who was injured in no-man's-land but that he in fact ran away. The badly scarred Dr Schmidt is actually Gereon's brother, Anno.
