Her desperate attempts to return home are continually thawrted by the pro-Japanese general Han Taek-soo. One day, she meets a friend from her past, Kim Jang-han, now an officer in the Japanese army. Kim, who is also part of the Korean independence movement, plans a secret operation to move Deokhye and her brother Yi Un to Shanghai, site of the Provisional Government of the Republic of Korea.
A fictional story inspired by real historical figures, The Last Princess is a heart-rending film of a sovereign (brilliantly portrayed by Son Ye-jin) who will spend the remainder of her life attempting to reunite with her one true love: her homeland.
