At 80, Dutch architect Herman Hertzberger, one of the most influential designers of schools in the world, is still in a constant battle to see his ideas about the relationship between education and space implemented. The filmmakers accompany him on visits to landmark buildings he designed, in staff meetings and at conferences with clients about new projects. Hertzberger is unimpressed with the latest safety ordinances or the desire parents have to separate the school from the street and the surroundings. He believes that freedom of movement and maximum transparency are vital preconditions for healthy learning. Although he is disappointed with the discrepancies between his vision and reality, he also knows how to wield his authority, combined with a dose of humor, when confronting decision-makers.
