In 1909 a small band of Korean independence fighters including protagonist Ahn Jung-geun (Hyun Bin) plot to assassinate Japan’s first Prime Minister Itō Hirobumi. Their goal was to take a big step toward Korean independence and pull their country out from underneath Japan’s harsh rule. Hirobumi had just rejected Korea’s attempt at annexation, so in response a small group of Korean soldiers hatched a plan to eliminate this new threat.
