The film blends live footage with historical illustrations to survey the American Civil War, opening with a top-hatted man boarding a steam locomotive and rolling train wheels. Antebellum life appears through cotton fields and workers, a static portrait of Lincoln, a fortress illustration, and a bearded man's portrait. War arrives as uniformed men peer through foliage and scout the woods, soldiers march through forest and snow-covered grass, a steamboat crosses a river, and horse-drawn carts pass cannons. Combat is depicted through soldiers firing large wooden cannons from behind stone walls, men lying motionless in fields and cemeteries, and reenacted battles with running, firing troops and smoke rising over an illustrated burning city. Ceremonial and political moments include soldiers marching past a decorated podium, a top-hatted speaker gesturing behind a lectern, and a flag raised in a wide shot, while a white arrow traces movements across a map of the United States. Cavalry sequences show mounted soldiers dismounting, turning, and riding across fields before the film fades on a title card over a rural landscape and closes to black.
