World War 1: Paris is the target of nightly German bombings that become more and more deadly. In a time where radars don’t yet exist and pilots can be fooled by false illuminations, the French General Staff secretly builds a fake illuminated Paris to save people’s lives. After being put in charge of the concept and construction, electrical engineer Fernand Jacopozzi will do everything to succeed in his mission. This film showcases special interactions with a historian, writer, aviation specialist and the grand-daughter of the man at the heart of this unusual plan, and displays original documents and archives that draw you into this epic tale of a wartime project that has been forgotten from history - a project that deserves to be revisited for his ingenuity and creativity.
