My mom watched this movie long time ago, now she wants to find it but can’t recall anything except the description. So movie is set in Eastern Europe, where nazi soldiers are forcefully taking children from their homes to use them for experiments. There are these two friends, a girl and a boy, taken by them as well. The nazi soldiers turn this guy into a sadistic killer. Later he and his childhood friend somehow meet and the guy recognises her and doesn’t kill her. Later they even have a child, but the baby was sent away. And after that somehow the child and father happent to meet and that’s it. I really really hope you can help me find it. Thanks in advance
