The Nazis have just erected a 10-foot-high wall around the Jewish quarter in Warsaw, Poland, trapping over 400,000 people in a cramped, 1.3-square-mile area. The Warsaw Ghetto, as it's come to be known, is a prison, plain and simple. Behind its walls, Jews are forced to live in squalor, with little food, water, or sanitation. It's a deliberate attempt to break their spirits and strip them of their humanity. The ghetto's creation marks the beginning of the end for Warsaw's Jewish community, as they're gradually deprived of their livelihoods, possessions, and eventually, their lives. The writing's on the wall – the Nazis intend to eradicate them.
