Sergeant Klaus Eggers dies during a tank transport, and what initially looks like an accident turns out to be murder. Tom and Semir come across the 'Copia Honoris', a secret elite unit of the German army, to which Eggers belonged. It turns out that Eggers was responsible for cocaine smuggling in the unit and therefore had to die. After another member dies, the group falls apart. In the showdown, Tom and Semir confront Lieutenant Colonel Ringsdorf, who refuses to accept the defeat of the 'Copia Honoris'.
