Based on a short story of Ivo Andrić, famous Yugoslav Nobel Prize winner, this film is set in Sarajevo during WW2. Mento is a humble, poor Jew who runs a caffe. Stjepan is a man of unknown background, with no social or psychological dimension, who joined Nazis to leave any sort of trace behind himself.

The film tells the story of the Yugoslav destroyer Zagreb which fights against Germany in 1941, and how some of the crew members try to organise a mutiny to keep fighting when the commander is ordered to surrender.

The action takes place in a Bosnian town during the Second World War and shows how anti-fascist illegals try to protect their intelligence network from the Germans and their Ustasha allies.
