Berlin, 1923. inflation! Millions in your pocket, but nothing to eat. No wonder that philosophy professor Hendrik Lilienthal and Diana Escher, Max Planck's assistant, have no other way to help themselves than to secretly visit the potato fields around Berlin at night. But they are not the only ones, and suddenly they find themselves in front of a badly mauled corpse.

Fortunately, they manage to get the case transferred to Inspector Gregor Lilienthal, Hendrik's brother - and the extraordinary trio is back on the investigation. They quickly find out that the victim was wearing a white suit, but by no means a clean slate.

The investigations lead to thieves and black market dealers, to people at the edge of existence. One trace leads to the French-occupied Ruhr area, where clashes between Germans and occupiers, saboteurs and separatists are raging. When Diana ventures too far, she is in mortal danger.
