Confederacy Theory presents and unflinching portrait of the cultural war that has erupted around the confederate flag - a century-old symbol that threatens to divide the South like no issue since the Civil Rights movement. Using never-before-seen archival footage and exclusive interviews with politicians, pundits, activists, and scholars, Confederacy Theory traces the history of this symbol and its impact on Southern culture, history, and identity - from the Civil War to the frontlines of a modern-day secession movement.
