When Sidonie-Gabrielle Colette marries the successful Parisian author Willy, her life changes dramatically: she moves from rural France to bustling Paris and becomes part of the intellectual and cultural elite. Willy, plagued by writer's block, convinces his young wife to work for him as a ghostwriter. In her debut novel, Colette tells the story of a self-assured young woman named Claudine. A semi-autobiographical novel, published under Willy's name, becomes a bestseller, bringing him wealth and fame. Soon, more Claudine bestsellers—written by Colette—emerge, eventually leading to an entire brand. Gradually, Colette begins her struggle to overcome societal constraints and reveal herself as the true author of the successful books, claiming her works as her own.
