In 1988, Cynthia Beatt and the young Tilda Swinton embarked on a filmic journey along the Berlin Wall into little-known territory. The film is now an unusual document. 21 years later, in June 2009, Beatt & Swinton re-traced the line of the Wall that once isolated West Berlin. This film depicts this poetic passage through varied landscapes, this time on both sides of the former Wall.
