It is an South-Korean movie which takes place in South Korea's capital Seoul. It highlights the shady sides of the country including drug dealing and organ trafficking.

Cha Tae-sik (Won Bin) was one of the best agents in the South Korean intelligence service.

Well, I'm not going to tell you the end of the film because it is worth to watch it and to see what is happening and sometimes you'll be surprised. It is very touching to see that a person who is filled with bitterness is able to build up a relationship/friendship again and tries to protect them as good as it is possible.
