The 5th anniversary of the inner-German wall to West Germany and West Berlin is on the agenda. The necessity of erecting the border is illustrated by comparing the situation in 1939 and the situation in the summer of 1961 with regard to the "threat of intervention" by the Western powers. Berlin people and GDR border guards are interviewed.
