Zielone Lata plot
In 1939, three ten-year-old children became friends with each other in the Polish town of Sosnowiec. One boy is Polish, the other boy is Jewish and the girl is German. The Jewish boy's parents are murdered and he himself is injured and left for dead. However, he is saved by the other two children. The Polish boy sees his brother taken from his mother to be raised by an Aryan family, after Polish resistance members are found in his home and then shot in the street. The German girl leaves with her parents to live in Germany and her family wants her to only interact with children raised in Germany from now on.
