September 1, 1939. Sixty-year-old Janusz Korczak and the students and teachers at his Dom Sierot Jewish orphanage are outside enjoying a beautiful day in Warsaw. Hours later, their lives are altered forever when the Nazis invade. Suddenly treated as an outcast in his own city, Janusz--a respected leader known for his heroism and teaching--is determined to do whatever it takes to protect the children from the horrors to come. When over four hundred thousand Jewish people are rounded up and forced to live in the 1.3-square-mile walled compound of the Warsaw ghetto, Janusz and his friends take drastic measures to shield the children from disease and starvation. With dignity and courage, the teachers and students of Dom Sierot create their own tiny army of love and bravely prepare to march toward the future--whatever it may hold.
