At each edition of the Heritage Days, the Élysée, a place dear to the hearts of the French, breaks attendance records. Exceptionally, our cameras were able to film behind the walls of this palace for eighteen months. More than 800 people work there every day in the shadows. Among them, a hundred young recruits and apprentices are trained by the best specialists and artisans in the country. Because the Élysée is also the showcase of French know-how. Arthur, only 16 years old, takes his first steps in pastry making in the prestigious presidential kitchens. To the great pride of his family. Full of audacity, Arthur himself wrote to the chef of the Élysée to ask him for an internship. Since he was taken on, to be up to the task, even on weekends, the young apprentice has been training. A vocation is born. Virginie, 34, has been selected to join the Republican Guard at the Élysée Palace. In terms of close combat, the young woman still has a lot to learn. Virginie will experience a test that all new recruits dread: a fight with the president's bodyguard, Mike, in his dojo hidden in the heart of the Élysée Palace's underground. For the first time, the highly secretive Presidential Security Group (GSPR) has accepted the presence of a camera during several of the head of state's trips. Frédéric, in his thirties, has just joined this very closed unit, after four years with the GIGN. On the program: escorting the President and training with live ammunition, under the demanding gaze of the head of the GSPR, Georges Salinas. A former member of the Brigade de Recherche et d'Intervention (BRI), he led the assault against the terrorists at the Bataclan on November 13, 2015. Didier, who has been with the house for 32 years, is the linchpin of all events at the Élysée. From the council of ministers to receptions, he is in charge of all the logistics of the palace. We followed him during a particularly sensitive diplomatic summit, because the eyes of the whole world are turned towards the famous ballroom of the Élysée, where Angela Merkel and Vladimir Putin will meet. A summit with a somewhat unusual flavor for Didier: after 3 decades in the service of the presidency, he will leave the palace. Before his departure, the head of logistics has one last challenge: to prepare the next generation. The presidential palace crosses history thanks to the know-how of the best craftsmen. We filmed the restoration of one of the most prestigious rooms, the Portrait Room. Marie-Laure and Astrid are responsible for the furniture, fabrics and works of art for the presidency of the Republic. After the work, they will be the ones to fit out and decorate this living room where President Macron has his habits. From the ceremonial rooms to the President's office, not to mention the underground galleries and the 15,000 m² of garden, we exclusively shared the astonishing daily life of these women and men who work behind the scenes of power.
