Trump dreams of a barrier against immigration from Mexico become architecture. And we join in the dream. But do we dream in beige or blue? Do we dream with horizontal or vertical stripes, in reinforced concrete or disarming steel? Eight design prototypes are competing here, made ridiculous by the unlimited nature of the landscape and grounded by test climbers that pull themselves up these monoliths. A brilliantly filmed and conceived documentary joke – without the relief of laughter.
