Based on Adam Hochschild book "King Leopold's Ghost: A Story of Greed, Terror and Heroism in Colonial Africa", the film covers an atrocious piece of history that is every bit as bad as the subtitle infers. Set at a moment when European countries were racing to find ways to carve up the natural resources of Africa, Leopold became the world’s richest man with billions stashed in secret bank accounts by gaining private ownership of the Congo Free State, and inserted a mercenary army to cruelly plunder rubber and ivory. He forced the locals to harvest it. Those who refused were dismembered or worse, and the book estimates that as many as 8 million were killed in this ruthless pursuit.
