Belgrade, 1943. All fronts are tapering. The Chetniks have already mobilized everyone from 18 to 45. The Germans are more determined than ever, the Russians aren't getting sober for years, the Czechoslovakians are practicing the action 'Over Skoda to freedom', the Apaches have bad breath... In such situation, Prele and Gluhi get the task to operate urgent mobilization of the entire manhood left. In short notice, they manage to get the first twenty to the given address! Twenty what!?
