The final season of the multi-awarded international hit series set in 1930’s Berlin.

Berlin, January 1933: With Hitler’s appointment as Reich Chancellor, the darkest chapter in German history begins. Charlotte Ritter investigates a series of murders targeting former front-line soldiers. The connections and motives reach back to 1918. An explosive file has disappeared, one that casts Hitler’s time as a soldier in the First World War in a new light. Politically incendiary material – and those involved seem willing to stop at nothing to get their hands on the file… even murder. When Gereon Rath suddenly vanishes without a trace, Charlotte does not know whether she will ever see him again.
