In 1988, Tilda Swinton toured round the Berlin Wall on a bicycle - starting and ending at the Brandenburg Gate - accompanied by filmmaker Cynthia Beatt. As Swinton travels through fields and historic neighborhoods, past lakes and massive concrete apartment buildings, the Wall is a constant presence.

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.
