Sky (1962)

Original title: Ουρανός

During the cold spring of 1941, with Greece already under German occupation, a long-suffering squad of war-battered soldiers receives orders from the headquarters in Athens to fall back, leaving behind the Albanian Front. As the men retreat through the snow-covered landscapes of the bomb-scarred Greek countryside, the terrifying certainty that nothing will ever be the same again crushes their weary human souls.
