Plot Outline:

Based on a true story, a group of allied
escape artist type prisoners of war are all
put in an 'escape proof' camp. Their leader
decides to try to take out several hundred
all at once. The first half of the film is
played for comedy as the prisoners mostly
outwit their jailers to dig the escape tunnel.
The second half is high adventure as they use
boats and trains and planes to get out of
occupied Europe
