Paula, a young supporting character, studies at the Main Character School and dreams on graduating to become a lead.

Shortly after the end of the Second World War: In 1945 and 1946, the men of the British "War Crimes Investigation Unit" drove through northern Germany on the hunt for Nazi criminals. One of them is Captain Anton Walter Freud, the grandson of Sigmund Freud, the founder of psychoanalysis. Anton Walter Freud fled to London with his family from the Nazis in 1938. Now an intelligence officer, he's back to track down killers on Allied wanted lists: hitmen in pinstripes, brutal SS henchmen, and ruthless doctors who conducted medical experiments even on children. The soldiers who witnessed the liberation of the Bergen-Belsen concentration camp months earlier are not squeamish about it. 24-year-old Freud is a free spirit known for his unorthodox methods. He knows how to make war criminals talk. So he comes across a crime that has hardly been known before, the murder of 20 children in Hamburg in the last days of the war.

Nothing special happens in the quiet, peaceful, and sad German city of Anröchte. Until the day in which its residents’ daily lives are disrupted by strange events: Hun knights armed with sabers perpetrate an arbitrary massacre for no apparent reason, decapitating people at random. Inspector Konka arrives in town to solve the mistery, along with his faithful assistant Walter, a philosopher type who reflects on the human condition as he wanders the melancholic streets of Anröchte.

Beneath the decadence of 1929 Berlin, lies an underworld city of sin. Police investigator Gereon Rath has been transferred from Cologne to the epicenter of political and social changes in the Golden Twenties.
