Overview

A soldier runs amok in a school. Military police and SEK take aim at the heavily armed man. Suddenly he is shot dead, but none of the snipers fired the final shot. Inspector Bischof is tasked with finding out who killed the soldier. The soldier was stationed in the very barracks that is under the command of Lieutenant Colonel Ralf Bischof, Kathrin's husband. An officer from the Military Counter-Intelligence Service is assigned to assist her in the investigation. Kathrin bites into the case. She finds out that the dead soldier was taking part in a series of scientific experiments testing methods to prevent anxiety. This research project is being led by her sister Ariane, a renowned psychiatrist. Kathrin's investigation puts her in extreme danger.
