In this walk, Alÿs strolled through what he referred to as the typical city of conflict. His route somehow followed the village in Jerusalem of the ceasefire demarcation line1 separating Palestinian and Israeli communities since the end of the 1948 Israel War of Independence.

Alÿs used 58 liters of green paint and traced the line of nearly 24 kilometers, passing through Jerusalem, as filmmaker Julien Devaux filmed. He walked past security control pasts and barriers that limit the movement of city dwellers depending on where you are from, but mostly those of Palestinians. Alÿs topped at various intervals to refill his can with green vinyl paint. What is extraordinary about the footage is that a few onlookers engaged with the artist, including security officers, at various checkpoints.
