The young Viktoria Schneider is shot dead during an art performance. It quickly becomes clear to the chief inspectors Kappl (Maximilian Brückner) and Deininger (Georg Weber) that only a trained marksman could have committed this murder, because the shot was fired from a long distance. Since the performance also critically dealt with the engagement of the Bundeswehr in Afghanistan, the suspicion soon falls on a group of four traumatized soldiers. A clear indication are videos of their therapy sessions, which theartist used for her performance. So each of the four has a motive. Nevertheless, the investigation is difficult because the soldiers form a strong camaraderie and give each other alibis. For Kappl and Deininger, the question arises as to how they can crack this tight-knit group.
And last but not least, the investigations in the soldiers' milieu also sparked controversy between the commissioners. Because they have very different views on the deployment of the Bundeswehr in Afghanistan.
