At the end of the 19th century, when the European powers divided Africa for themselves, King Leopold of Belgium carried out a brutal sacking of the territory surrounding the Congo river that provoked the death of over 10 million Africans. A rich and perturbing story, it describes a megalomaniac of monstrous proportions. It is also the moving portrait of African rebels who did not kneel and a handful of valiant missionaries and explorers who traveled to Africa in search of adventure and instead became witnesses to a genocide.
