Assassination
In 1911, during Japan's rule over Korea, a resistance fighter named Yem Sek-jin tries but fails to murder the governor-general and a pro-Japanese businessman named Kang In-guk. That evening, Kang discovers that his own wife was helping Yem. Kang kills his wife but a wet nurse runs off with one of his twin daughters. By 1933, there are over 30 Korean independence factions operating in Korea, China, and Manchuria. Yem has become a captain in one of these factions, but his colleagues are unaware that he is secretly reporting to the Japanese, since back in 1911 he was tortured by the Japanese into submission.
Yem meets with some Korean politicians in Hangzhou, including Kim Koo and Kim Won-bong, and is asked to gather three delinquent resistance members— Big Gun, Duk-sam, and Ahn Okyun— so they can enter Seoul and assassinate Kang, along with a general named Kawaguchi Mamoru. After bringing them to Shanghai, however, Yeom sells this information to the Japanese. The Japanese attempt to find Ahn, but a skilled contract-killer named Hawaii Pistol decides, on the spur of the moment, to pretend that Ahn is his wife, allowing her to elude the soldiers.
Kim Koo questions Yem's loyalty giving Yem's subordinates, Myung-woo and Se-gwang, orders to kill him if he is a spy. However, Yem manages to come out the victor instead. Additionally, Yem hires Hawaii Pistol to intercept and kill the three resistance members, telling Hawaii Pistol that they are Japanese spies, anticipating a great reward from the Japanese. As Hawaii Pistol and his assistant Buddy travel to Seoul, they befriend Kawaguchi's son, who is a lieutenant in the Kwantung Army. In Seoul, Hawaii Pistol locates Big Gun and shoots him as he is running. With Big Gun missing, Duk-sam and Ahn proceed with the operation, hoping to ambush their targets at a gas station. To their misfortune, the car is a decoy and both Duk-sam and Korean sympathizer Kimura are killed in the attempt. Ahn is then ambushed by Hawaii Pistol, but he recognizes and spares her, and even sympathizes with her mission, since he is himself a Korean.
Ahn discovers that she is Kang's missing twin daughter. The other daughter, who happens to be engaged to Kawaguchi's son, recognizes Ahn and visits her apartment, but is killed by her father Kang, Yem and a group of soldiers. The latter are none the wiser and believe they have successfully killed Ahn. At this point, Ahn assumes her twin's identity, and a few days later, enters the wedding as the bride. Assisted by Hawaii Pistol, Buddy, and Big Gun— who survived his injuries— they carry out an attack on the wedding. Ahn kills Kawaguchi, and Hawaii Pistol kills Kang when Ahn hesitates to do so, revealing that he killed his father, a Japanese sympathizer, and did not want Ahn to live with that and become a mercenary like him. Big Gun is killed while covering their escape, taking Kawaguchi's son hostage, they are hemmed in by army reinforcements. Hawaii Pistol, realizing that she can still pose as her twin, shares a kiss with Ahn, promising to meet her again in the cafe they met in Shanghai. Ahn walks out and is rescued by the Japanese soldiers— she later absconds back to Shanghai. Hawaii Pistol and the Buddy attempt to escape but Yem kills them.
For his services to Japan, Yem is made head of the secret police. However, the Japanese are defeated in World War II and Korea is liberated. In 1949, a commission for war crimes investigates Yem— now a senior officer with the Korean police— who protests his innocence and points to his resistance service. The only witness to Yem's guilt is found murdered, so the charges are dropped. Even so, Yem is cornered on the streets by Ahn and Myung-woo who, it is revealed, had survived his massive injuries but was rendered mute and slightly disfigured. They proceed to shoot Yem and he dies. Ahn sadly recalls the memories of her friends in the Resistance, Hawaii Pistol and Buddy before the screen fades out.
