Based on an actual escape from East to West Germany staged on January 28, 1962, this routine docudrama by director Robert Siodmak re-enacts the tale. Kurt Schroeder (Don Murray) is a chauffeur, the young East Berliner who gets the idea of digging a tunnel underneath the Berlin Wall. Thus well-assured that no guards will be able to see him escaping, Kurt carefully implements his plan. But he is not thinking of himself alone, and when the time comes to use the tunnel and leave East Germany behind, he takes his family and a few dozen other people along with him.
