Opening in the fall of 1929 Berlin, during the tumultuous weeks before Black Fridays stock market crash, the third series sees Inspector Gereon Rath and Charlotte Ritter assigned to investigate the death of an actress, only to realise that the film industry is as rotten as the underworld. In the meantime, the Black Reichswehr are regathering their forces for their next attempt to bring down democracy and provoke more clashes with the Communists.
