I think I've mentioned the book "Slavery by Another Name" here before. It won a Pulitzer. It tells the story of how many black men in the South were kept in forced labor until World War II, despite the 13th Amendment. I just learned that there's a new documentary based on the book premiering tonight on PBS:

If it's anywhere near as good as the book, it's a must-see.
