I watched it when i was a lot younger, at school. It was about Auschwitz concentration camp. It must be quite an old film so it wont be Schindlers List.
I remember there were women in a sewing room and one hid her baby in a cupboard from the guards but the baby cried and was found.
It also showed a queue of people lining up to go in the gas chambers. And it showed what else went on. It was educational. My teenage niece is doing something at school on this subject and i suddenly remembered that film which i saw and i think it would help her a lot with this project.
