Born minutes apart in 1843, twins Jacob and Jack Underwood are separated by fate and raised on opposite sides of a divided nation. One grows into a Confederate soldier loyal to home and soil; the other becomes a Union man devoted to preserving the nation. Neither knows the other lives—until Gettysburg. Amid smoke and chaos, they come face to face, identical strangers bound by blood and circumstance. In a war that demands loyalty above all else, the brothers must choose between duty and kinship, proving that survival often leaves the deepest wounds.
