The illegitimate son of a famous architect seeks the father he never knew. The architect is Louis Kahn, who co-founded modernism -- naked concrete, glass walls, etc. Kahn was a late bloomer, an unemployed artist who was 50 years old when, on his first trip to Rome, he had a revelation of how to create an entirely new monumental style of architecture: make it look like ruins from the future. Kahn was an elusive nomad, traveling constantly and fathering three separate families, with three "wives," each of whom was weirdly (even delusionally) faithful to him. After a few decades of sleepless striving to make great buildings, Kahn died bankrupt, alone and unidentified in Penn Central Station, New York. His son Nathan, whom he rarely saw, was only 11. Now an adult, Nathan sets out to find out who his mysterious father really was by investigating the only thing his father left behind -- his buildings. In a very emotional and satisfying climax that takes place in Dacca, Bangladesh of all places, Nathan finds what he is looking for. At this same climax scene viewers find out that his father Louis really was as great an artist as his contemporaries believed. Along the way in this odd family saga, you get a fabulous lesson in modern architecture.
