Karl Lagerfeld and Sebastien Jondeau met in 1997. The dream of a young man of humble origins comes true and from that moment on he will never leave the fashion designer. Jondo becomes the designer's driver, bodyguard, assistant and close friend. Lagerfeld opens up a world for him that he, a working-class child from a Parisian suburb, would never have known otherwise: he flies with him on private jets to important fashion shows in New York, Milan and Paris, accompanies him on holidays in luxurious villas, meets famous world celebrities and the most influential people in the fashion industry. Lagerfeld becomes a father figure for Jondeau, a role model to whom he will be devoted until the end of his days.
