As part of her series tracing the crucial turning-points of the early Cold War, Bridget Kendall tells the story of the crisis that led up to the building of the Berlin Wall. By 1961, so many were fleeing communist East Germany that the country was in crisis. So the government built the Berlin Wall to stop them. Would-be escapees were regularly gunned down. Bridget hears the stories of three people who successfully fled East Berlin - one before the Wall went up, two who pulled it off even with the Wall in place. And she finds out why they wanted to leave East Germany in the first place. With: Leslie Colitt, Gisela Nicolaisen, Joachim Rudolph Producers: Phil Tinline and Sabine Schereck.
