Dušan, a young deputy war crimes prosecutor, is given the task to investigate a paramilitary formation, the First Pioneer's unit, that was operating on the battlefields in Croatia, Bosnia and Herzegovina and Kosovo, where they disappeared without a trace. Dušan is determined to bring the case to an end and to show his father, a famous retired professor at the law faculty, but to his boss too, that he is capable for this job. This becomes for Dušan much more than a simple case – it becomes a personal confrontation.
