Synopsis
West Germany, and West Berlin, become more affluent, prompting a surge of East Germans to cross the borders in Berlin, kept open under the Four Power Agreement on Berlin. Khrushchev's demands that the Americans, British and French leave Berlin are opposed, and prospects for a peaceful resolution are dashed after the Soviets pull out of the Paris Summit in 1960 as a response to the U-2 incident. Overnight on August 12, 1961 East German police and military units divided the city of Berlin, and work commenced on building the Berlin Wall. Initial tensions culmulate in a stand-off between US and Soviet tanks. Kennedy visits Berlin in June 1963 and delivers his Ich bin ein Berliner speech. Interviewees include Anatoly Gribkov, Valentin Falin, Stefan Heym, Egon Bahr, Raymond L. Garthoff and Conrad Schumann. The pre-credits scene features East Berliners seeking to flee into the West.
