He has endured more than any child ever should, but now he must survive Block 66.

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

At Buchenwald, the new arrivals are assigned to their barracks. Kinder Block 66 is to be Moshe's new home, but he doesn't yet realize just how significant this placing will turn out to be. For just a short time later, the Germans decide to destroy the camp and send its remaining inmates to the death march once more - but they are not prepared for Buchenwald's secret resistance, which rises up with one mission: 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.
