Based on the biography Ne jamais rien lâcher, the script traces the career of Marinette Pichon over three decades. Born in 1975, she was the pioneer of French women’s football and one of the greatest stars of that sport in the world. A prodigy discovered at the age of five, she went on to become the first French player to make a career in the United States (men/women combined) and the record holder for the number of goals and selections for the French team (men/women combined). From her childhood, ravaged by an alcoholic and violent father, to the American dream (she was crowned best player and best scorer in the prestigious US league in 2002 and 2003 and “Most Valuable Player” in 2003), via her career with the French team, Marinette paints the portrait of a kid from a working-class background who was not destined for such an extraordinary career path…

A life of an ordinary Parisian teenager Marinette goes superhuman when she becomes Ladybug. Bestowed with magical powers of creation, Ladybug must unite with her opposite, Cat Noir, to save Paris as a new villain unleashes chaos unto the city.

On school break, Marinette heads to Shanghai to meet Adrien. But after arriving, Marinette loses all her stuff, including the Miraculous that allows her to turn into Ladybug!
