For five months, from D-100 to September 8, 2024, Jules and Gédéon Naudet follow behind the scenes all those who make the Olympics happen. Their cameras gain access to the office of Tony Estanguet, three-time Olympic canoeing champion and President of Paris 2024, to the competition venues under construction, to the layout of the athletes' village, to the route of the Olympic torch relay, to the water treatment infrastructure of the Seine... bearing witness to the full complexity of the organization and deployment of the Games of the XXXIII Olympiad. This behind-the-scenes look highlights the commitment of all those who work on a daily basis to make this event a sporting and popular success, encouraging the transmission of the Olympic and Paralympic legacy. For it is through the eyes of privileged witnesses that the Frères Naudet tell the story of this final stretch, first and foremost Tony Estanguet, but also the operational teams of Paris 2024, those of the torch relay, the volunteers, the supporters of the French team and the forces of law and order... All at the service of the world's greatest event.
