is the year 2008, and Mordparta detectives have the oldest case they have ever encountered on the table. The basic rule of their work is that the sooner they get to the case, the greater the chance of capturing the perpetrator. This time, however, this is a case that happened fifty -five years ago: they have checked the opportunity to accuse the then border guards of murders in the case of shooting in a population trying to emigrate to Austria. In the end, there are many more cases than the detectives originally thought. They chose one of them: the death of five people (including two children) on a barbed wire near Petržalka in 1952 at that time in society, because it was not allowed to write about it, but fortunately changed. Everyone has to immerse themselves in a mixture of spy games with detective overtones, essence of suffering with fascinating blood, hatred and fanaticism.
