Shoah: Four Sisters (2018)

Paula Biren, Ruth Elias, Ada Lichtman, Hanna Marton: Four Jewish women, witnesses and survivors of the most insane and pitiless barbarism, and who, for that reason alone, but for many others also, deserve to be inscribed forever into the memory of humankind. What they have in common, beside the specific horrors to which each of them were subjected, is a searingly sharp, almost-physical intelligence, which rejects all pretence or faulty reasoning. In a word, idealism.
