Actor David Jason examines wartime escapes that inspired films and TV dramas. He begins his journey in Germany at Colditz Castle, where William Neave tells how his father Airey fled dressed as a German soldier. He then heads to Poland to visit the setting for The Great Escape, where former Stalag Luft III internee Ken Rees describes how he helped dig the tunnel immortalised on the big screen. David also meets a Frenchwoman who sheltered an escaped Briton - and learns how a love story developed.
