January, 1945. 14-year-old Moshe Kessler steps off the train at Buchenwald concentration camp. Having endured the horrors of Auschwitz-Birkenau, lost touch with his entire family, and survived the death march in the freezing European winter, he has seen more than his share of tragedy.

Moshe knows only one thing about Buchenwald. Everyone knows it.

If you want to survive, you have to get to Block 66.

The Germans are cruel and determined – but they are not prepared for Buchenwald’s secret resistance, which rises up with one mission only: to protect the camp’s children from harm.

This is the incredible true story of Moshe Kessler and Block 66 – the children’s block that was at the forefront of one of the most shocking and inspiring stories of Holocaust survival.
