Paris, 1853. The gloomy, centuries-old city is undergoing the most important and splendid redevelopment in the history of modern urban planning. Day by day it is being transformed from a muddy, foul-smelling city languishing by a polluted river into a magnificent world capital. An explosive, tireless powerhouse is directing the massive task. He is Baron Georges Haussmann, a brilliant municipal administrator appointed in a matter of minutes during his first meeting with Emperor Louis Napoleon III to rid the medieval city of its soot and squalor and beautify its every corner. "Build me a city!" the Emperor commands Haussmann at Saint-Cloud. It is as Baron Haussmann begins his work and organizes his staff that he writes to Charles Fabron, a grieving young widower and successful architect in Rouen, offering him a position in his newly formed Offices of City Planning.
