Archaeologists and veterans hunt for the tunnel the Germans never found, and reveal the epic scale of the POWs underground exploits. On the 24th March 1944 the most famous prisoner of war escape in history took place. It was immortalised in the classic film The Great Escape, yet the real story of the mass breakout from Stalag Luft III is stranger than fiction, it was an incredible operation involving hundreds of Allied prisoners digging three huge tunnels right under the noses of their German guards. But what started off as an adventure would end in tragedy, and the rules of the game would be changed forever. This is the story of The Real Great Escape.
