"Story of youths during the German occupation of Poland in the World War II who come to adulthood through love and adversity." This late 40s film tells the tales of the Polish plight during the war years that were not far off and with wounds still fresh. It is an amazing flick and show the horror that was Poland during WWII. Couldn't find a trailer for it but below is a short scene of it so take a look.
An incredable flick,
Novel by Bohdan Czeszko in which the film was based.
