Bertolucci’s well-regarded “Last Emperor” offered some insight into Japan's ambitions in Manchukuo, though fewer films explore their parallel efforts to dismantle Korea's government. During the Joseon dynasty, their last emperor refused to acknowledge Japan’s annexation of his country, and as a result, something harmful was introduced into his drink. This left his daughter, Deok-hye (played by Son Ye-jin), vulnerable to the control of scheming advisors who arranged for her transport to Japan under the guise of being incorporated into the Japanese Imperial family. Initially utilized to aid their political machinations, she quickly becomes repulsed by how Koreans are exploited and mistreated by the new regime, prompting her to rebel and seek a path back to her homeland. Even after Japan’s defeat, her chances of returning seem bleak, as the newly formed Korean republic is unwilling to encourage any possibility of restoring the monarchy, so she remains barred from her native land. Will she ever be allowed to go home? It's a skillfully made historical piece that effectively portrays a situation where a courageous young woman is pressured through threats against those close to her and her people while World War II unfolds and political goals remain unmanaged. Son Ye-jin gives a strong performance, and the rest of the actors provide us with moments showing the grandiosity and resistance movements that defined her adult years. While it’s based on certain historical events, much of it is imagined drama, which still works well in depicting a remarkable woman who could have easily chosen an easier existence if she had simply complied.
