The winter of 1945, the First Bulgarian Army is engaged in the battles for the liberation of Hungary from the Nazis during the Second World War. Three men are sent to join the army, but they are completely unprepared and without a clear idea of warfare. They are laughable with their inability to cope with their tasks.
