Berlin, 1922: Hunger and poverty still dominate the streets, the devaluation of money is advancing, political assassinations shake the country.

In Grunewald, the body of a young man is found who was shot and buried nine months earlier. Inspector Gregor Lilienthal is determined to find the murderer, even though the traces have long since cooled off. His brother Hendrik, a professor of philosophy at the university, and Diana Escher, Max Planck's physics assistant, support him in this with philosophical wit and scientific thoroughness.

As it turns out, the dead man belonged to the notorious organization Consul, an association of former Freikorp soldiers who fight the young republic with terror and violence. Walther Rathenau is next on their hit list. In a race against time, Hendrik, Diana and Gregor try to uncover the conspiracy and prevent the attack. But the assassins are always one step ahead of them.
