Murder in an ICE train on the Ulm-Stuttgart line. The train comes to an abrupt halt at Geislinger Steige. A man flees in panic and disappears into the steep slope of the Swabian Alb. Inspector August Häberle is in the dark for a long time: He knows neither who the shot man is, nor whether the fleeing man murdered him. His only clue is the dead man's notebook. But do the addresses of doctors and pharmacists contained in it really lead to the perpetrator? Häberle runs out of time, because the very next night he finds another corpse.
