This movie has a simple premise, very much like the Hollywood film Taken. The story also uncovers a pretty grisly drug and organ trafficking industry, and the way they operate, as well as the unscrupulous methods they use to avoid detection. Won Bin is an ahjusshi on a mission. Even though the relationship between him and the girl drives the movie, they share surprisingly little screen time. Most of it is spent on him while on the chase, some of it on the villains, then some of it on the police who are on the chase for this mysterious ahjusshi and the traffickers. The action scenes are pretty exciting and I appreciate the camera work and varied angles used to give us a good idea of the frenetic pace of the fights. I would not watch this again, if only for the gory and bloody scenes that are pretty hard to swallow. If any at all, its rewatch value probably lies in the subtly quiet and moving moments between Won Bin and Kim Sae Ron. Won Bin seems to be quite fussy about what he works on. My guess is he will not return to K-dramaland which is frantically paced and hence exhausting. This makes every film and TV drama he has ever worked on even more precious.
