Seoul

Detective Hayase Yutaro has been sent to Seoul to bring a convict from Japan. On his way back to the airport, he gets involved in a robbery and has to kill a man in order to survive. Hayase is forced to extend his stay to help identify the escaped car driver. As a detective, he cannot hold back and finds himself getting more and more interested in the robbery cases which happened in Seoul in the last few months.

Kim himself is saddled with obstructive KCIA guys who regularly overrule his authority.
