The episode of Ulisse: il piacere della scoperta, by Alberto Angela, is dedicated to the story of one of the most shameful events in the history of our country: the roundup of the Jews in the Rome ghetto which took place on 16 October 1943. It all began with the laws racial groups, which from one day to the next had deprived thousands of Italian citizens of many rights and freedoms simply because they were Jews. And it ended with the extermination camps from which very few had escaped after experiencing all sorts of horrors. Alberto Angela will tell the story of the events in the same places where the tragic events took place. The strong point will above all be the direct testimony of those who escaped death in the concentration camps, certain that listening to their voice will be a renewed opportunity for reflection, analysis and knowledge for viewers. Among the testimonies is that of Senator Liliana Segre.
