During WWII, Allied prisoners of war were always looking for ways to escape. One such place dedicated to that effort was Ft. Hunt, Virginia. Known only as a post office box number during the war, this highly secretive place was also an intelligence center. It's main goals were to send the prisoners packages which contained hidden devices to gather intelligence on the enemy forces and to aid in their escape efforts. This program also includes interviews by former members of Ft. Hunt who were sworn to secrecy.
