Radio Free Europe:A search light illuminates a barbed wire fence. Tracking shot of railway tracks. A railway crossing barrier comes down. Soldiers by on duty by the tracks. A farmer works in a field with a horse. A watch tower in the background. Windows on a street. Armed soldiers on the road. Barbed wire fences with fields and hills beyond them. A search light illuminates a barbed wire fence. The words ‘The Iron Curtain isn’t Soundproof’ read on screen.
