Brutal terrorist T was a government agent until his agency used him as a pawn against his will, turning his own government against him. Now, his former government associate, Jay, is on his trail. They will come to blows during a busy weekday rush hour when Jay's would-be girlfriend, Kay, calls him from a subway train to notify him that T has boarded the train with a large amount of explosives--which he threatens to detonate unless his demands are met. This big, Western-style Korean action film is the directorial debut from Baek Woon-hak, who was an assistant director on the internationally successful SHIRI (2002).
