　　In the Civil War, Union soldiers are about to hang a defiant Confederate planter from a bridge, for sabotage. The noose is placed around his neck, but the rope breaks and he plummets from the bridge into a river. Dazed, he swims the rapids downstream, while the soldiers fire at him. He clambers on a river bank, and excitedly starts his journey back to his family plantation.
