Senke nad Balkanom plot
Belgrade at the time of the turbulent 1920s is the center of conflicts of interest from different parts of the world. In the second half of 1928, in a rather controversial political and social climate, the opium trade is marked by a series of ritualistic, inexplicable murders that make the public shudder. Two police inspectors, Dragan Bjelogrlic and Andrija Kuzmanovic, are tasked with solving these murders.
