The plot summary on the website that I watched it on was incredibly vague which made me a bit hesitant to watch the movie. However I don't regret giving it a chance, not at all. It doesn't beat around the bush and waste time with backstory buildup but is packed with a punch right from the start. Intrigue. Mystery. Suspense. All in the first fifteen minutes.The details are filed in as the film progresses in a believable and intriguing fashion. The plot-lines were cohesive, well thought out and the scenes were well shot. I hadn't seen Nishijima Hidetoshi in anything before but I can honestly say that I look forward to his next film. I was moved by his acting in a way that I hadn't expected to be. Great work. Very touching. His character was so convincing that I honestly hurt for him. The female lead was level headed and enjoyable to watch. She was beautiful, calm yet realistic. The previous user said that it seemed that they tried to pursue some sort of love-line and failed but I have to say that I disagree. Instead I would describe it more as a tragedy for all the parties involved. It can't be compared to the typical forced love-lines thrown in the usual action/thrillers just for the sake of it. For me, it fit quite well. If I went into any more detail I would spoil it for you so I'll just leave it like this: I would recommend this movie. Definitely. From the action, casting choices and the way they balanced the whole Japanese/Korean concept, everything was great. Just watch it. You wouldn't regret it.
