From the firing on Fort Sumter to the iconic battlefields of Manassas/Bull Run and Gettysburg, the mecca of reenacting, find out how far they're willing to go to relive history. Travel back in time with them to document how the Civil War was lived, felt and fought. Through the experiences of three unique characters - a former Marine who served in Iraq, a teenager bent on joining the elite ranks and a man who claims to be the reincarnation of a Gettysburg soldier - we get a candid look inside this deeply passionate community, and emerge with a new understanding of the sacrifices we made as a nation to preserve the Union.
