It is 1933 and a dead man has been found lying under railway arches in Berlin. An old soldier, hideously disfigured, he has been killed mysteriously. Gereon Rath is brought onto the case while his fiancée, Charlotte Ritter, blazes her own trail. Meanwhile, the Nazis consolidate their hold on power, the Reichstag is burned down, and things become a lot worse not only for Berlin's Jewish community but also for those police officers who can remain in action.

Berlin,1931. A power struggle is taking place in Berlin's underworld. The American gangster Abraham Goldstein is in residence at the Hotel Excelsior. As a favour to the FBI, the police put him under surveillance with Detective Gereon Rath on the job. As Rath grows bored and takes on a private case for his seedy pal Johann Marlow, he soon finds himself in the middle of a Berlin street war.
Meanwhile Rath's on-off girlfriend, Charly, lets a young woman she is interrogating escape, and soon her investigations cross Rath's from the other side. Berlin is a divided city where two worlds are about to collide: the world of the American gangster and the expanding world of Nazism.
