Plunging into decades of historical research, Josephine is useless in front of her elegant, beautiful, radiant sister, Elise: no pain from her parents, no love from her sister, no respect for her daughter, and her husband simply eloped to Africa with his lover to raise crocodiles. At a regular dinner party in an upper-class society, Elise falsely claimed that she was writing a historical novel, and the publishers present immediately expressed their willingness to publish it to her. Elise, who could not write a masterpiece, was forced to ask Josephine for help. Due to economic hardship, Josephine agreed to catch the knife, but as soon as the work was published, it made the whole Paris boiling and completely subverted the lives of the two sisters.
