Blackmon's Pulitzer Prize-winning book, the film illuminates how in the years following the Civil War, insidious new forms of forced labor emerged in the American South, persisting until the onset of World War II.
The Plaszow concentration camp in Poland makes a good example of the forced labour the Jewish prisoners underwent during internment. This misuse was common throughout internment camps during the holocaust.
