During the Yugoslav break-up, Federal Army officer is fed up with war and takes some leave in Belgrade. However, it turns out that he is less haunted by war horrors than with some sentimental skeletons in the closet. He meets his former comrade and best friend who is AWOL, but can't report him because he had an affair with his wife.

Taking place just after the end of Bosnian War, the series is mostly set in a kafana named Složna braća owned by Halimić brothers and located on a small patch of UN-controlled territory (covering 0.0657 km2) not claimed by any of the three warring sides. Serbs, Bosniaks, and Croats, otherwise very hostile to each other following a ferocious civil war, regularly visit the said kafana in no man's land in order to arrange mutual black market activities (weapons and food trade, oil and cigarette smuggling, etc.). When the word gets around about an important weapons shipment passing through the territory that can supposedly completely change the division of power in the Balkans, the place becomes a lively hub of espionage, deal making, and skulduggery.
