A tender film that follows the daily routine of the 93-year-old architect Gottfried Böhm, renowned for his concrete architecture, such as the brutalist church in Neviges. Gottfried was the son and grandson of architects, and his three sons are also architects. This unique family represents a nice cross-section of German architectural history. The film documents encounters with his family and former colleagues and reveals the inspiration behind his work. The choices of the three sons sometimes create tension between father and sons. And then there is the woman, the mother of the boys, also educated as an architect. An intimate and splendidly filmed portrait of a marked family that has made its mark.
