The movie is a cross section of the World War I, exposing its senselessness, in a different manner but still on the same level as Remarque's classic (All Quiet on the Western Front).
The movie shows only a short period of a small commando. The title (literally "Grey Nobodies") reflects the uniform of the soldiers in the foggy season as well as the soldiers' insignificance together with the mission's insignificance. Somehow, in contrast with all this grayness, viewers can touch the tension. Walk of the small group, hardly carrying their equipment, exhausted and starving, out of ammunition, guarding the ragged camp ... reminded me veteran classics in best US war movies.
Having survived perhaps years in the war, personality of the soldiers are not anymore hidden beneath the army discipline. Strong characters, their desires and fears, their past and fate, everything becomes framed in a kind of finale I would not spoil here.

Update: the one-hour film was financed by a World War memorial program and shown on a TV channel. It seems to be available (in full HD) on the most popular video sharing service under its original Hungarian title.
