In the film, the worst kidnapping and hostage crime case of the century occurs in Thailand by the hands of a criminal named Min Tae Goo (Hyun Bin). Korea's police forces call in the team's best negotiator Ha Chae Yoon (Son Ye Jin) in order to hold back Min Tae Goo from taking the lives of his hostages one by one, all the while tracking down his whereabouts. 

You can check out Hyun Bin's chilling transformation into a psychopathic killer below in the first official trailer for 'The Negotiation'. The film premieres in Korea during the Chuseok holidays, which kicks off on September 23.
