During the Second World War, there were about 250 British and French soldiers and airmen in a prison-of-war camp in Germany．As they had been imprisoned for so long, they had begun to write and perform plays and other shows．
This particular prison camp wasn' t like many other camps, however．It was a very old castle, and there were lots of tunnels and secret passages the prisoners had found but their German guards had not．
Since they had so much time, all of the acting lovers always managed to leam their lines by heart．The play they were going to perform on this occasion had been specially written to involve as many men as possible．Almost all of them were given parts to play and lines to leam so that many prisoners could gather on the stage at one time and hide easily from the audience．
The curtain went up on the first scene to show a weakly-lit bar in Chicago in the 1920s．As the play progressed, more and more men came onto the stage．
While three or four main characters were acting near the front of the stage, a crowd of the others stood and moved around the dimly-lit scenery behind．This was ideal because, while the play was going on, the prisoners were one by one climbing down a hole in the stage and crawling along a tunnel which led out under the border fence to escape into a small wood some 500 meters from the stage of the "theater"．
Fifty men left the stage through the hole during the performance, but the mass escape was unsuccessful．Most of the men were caught within a kilometer of the fence although two or three did manage to cover a few kilometers before they too were arrested．Although they failed in the escape, at least they enjoyed a certain amount of popularity with the other prisoners for a short time after their return．
