Staying In Place

As the episode starts, a group of Civil War soldiers are walking down a road as Rod Serling narrates:

This road is the afterwards of the Civil War. It began at Fort Sumter, South Carolina, and ended at a place called Appomattox. It's littered with the residue of broken battles and shattered dreams.

After a brief opening dialogue between the Sergeant and Lavinia Godwin, Rod Serling resumes:

In just a moment, you will enter a strange province that knows neither North nor South, a place we call—The Twilight Zone.
