Two decades after she first stepped into the royal shoes of Genovia, Mia Thermopolis (Anne Hathaway) returns in The Princess Diaries 3. Now a confident and compassionate queen, Mia is facing a new era for her country—one filled with political change, pressure to modernize the monarchy, and unexpected personal challenges. As Genovia prepares to host a high-profile international summit, Mia must navigate diplomacy, scandal, and a mysterious threat that could shake the nation’s future.
Meanwhile, questions about Mia’s love life resurface when a charming ambassador from a neighboring country catches her attention, just as familiar faces from her past begin to reappear. Torn between duty and desire, Mia must reconsider what she truly wants—not just as a queen, but as a woman. As her grandmother Queen Clarisse’s legacy looms large, Mia finds herself questioning her leadership and her heart.
With the help of old friends and a few new allies, Mia embarks on a journey that takes her back to her roots—including a surprise visit to San Francisco, where she reconnects with memories of the girl she used to be. Through laughter, royal blunders, and heartfelt revelations, she rediscovers the courage to lead with authenticity and heart.
The Princess Diaries 3 is a delightful and empowering continuation of Mia’s story—blending nostalgia, modern royalty, and personal growth. It celebrates how far she’s come, while reminding audiences that growing up is never truly finished—even for queens.
