The most memorable symbol of the revolution that swept across Europe two decades ago is the November 1989 opening of the Berlin Wall after 28 years. The Wall: A World Divided tells those dramatic events from the perspective of ordinary East Germans whose lives were caught up in the wheels of Cold War politics. And it presents the lesser-known story of how the autumn of 1989 set the stage for three world leaders - George Bush, Mikhail Gorbachev, and Helmut Kohl - to come together and guide the completely unanticipated spiraling series of events that ended the Cold War.
