Set at the beginning of the Civil War, Tap Roots is all about a county in Mississippi which chooses to secede from the state rather than enter the conflict. The county is protected from the Confederacy by an abolitionist and a Native American gentleman. The abolitionist's daughter is courted by a powerful newspaper publisher when her fiance, a confederate officer, elopes with the girl's sister. The daughter at first resists the publisher's attentions, but turns to him for aid when her ex-fiance plans to capture the seceding county on behalf of the South.
