Synopsis
Set during the Civil War, Free State of Jones tells the story of defiant Southern farmer, Newt Knight, and his extraordinary armed rebellion against the Confederacy. Banding together with other small farmers and local slaves, Knight launched an uprising that led Jones County, Mississippi to secede from the Confederacy, creating a Free State of Jones. Knight continued his struggle into Reconstruction, distinguishing him as a compelling, if controversial, figure of defiance long beyond the War.
