In the bustling countryside of France during the 1890s, a charming and refined white cat named Mewsette longs for a life of sophistication that she believes can only be found in the glamorous city of Paris. Feeling constrained by her simple rural life, she decides to embark on an adventure to the capital, leaving behind her love-struck suitor, a robust farm cat named Jaune-Tom, and his loyal sidekick, Robespierre. Driven by her dreams of elegance, Mewsette sets off alone, dazzled by the allure of Parisian high society.

Upon arrival in Paris, Mewsette quickly encounters Meowrice, a suave but conniving tomcat who presents himself as her guide. Meowrice keenly sees Mewsette's potential to become a show-stopping beauty and plots to use her innocent ambitions for his own gain. Meanwhile, Jaune-Tom and Robespierre embark on their own journey to find Mewsette and bring her back home safely. As Mewsette is drawn deeper into the sophisticated but perilous world of Paris, she begins to realize that not everything—or everyone—is as it seems. While exploring themes of love, ambition, and self-discovery, the story unfolds against a backdrop of vibrant animation and delightful music, culminating in an exciting and heartfelt adventure filled with lessons on what truly matters in life.
