A deeply moving, insightful and fascinating documentary on Louis I Khan, regarded by many as one of the greatest architects of the 20th Century, by his illegitimate son, Nathaniel Khan. Interviewing friends colleagues and mistresses (including his own mother) Nathaniel builds a complex image of an emotionally flawed genius. Many of Louis's greatest works, including Fort Worth's Kimbell Art Museum and the National Assembly building in Dhaka, Bangladesh, are given ample space in this impassioned journey of discovery.
