Director Ryoo Seung-wan (The Unjust, City of Violence) takes the helm for this stylish, sweeping action thriller centered on a mysterious North Korean "ghost" agent who goes on the run after being exposed during an illicit arms deal in Berlin. Jong-seong (Ha Jung-woo) does not exist -- at least, he doesn't according to the CIA and South Korean intelligence. Both agencies, as well as the North Koreans, are monitoring a tense, illegal weapons deal unfolding in a Berlin hotel when Jong-seong appears out of nowhere and chaos erupts. When the smoke clears, no one is certain whether Jong-seong is a double agent or merely a pawn in a much more diabolical game. But North Korean operative Myung-soo (Ryoo Seung-bum) is determined to find answers. When his investigation leads him to Jong-seong's wife Jung-hee (Gianna Jun), who works at the North Korean embassy in Berlin, the mysterious agent at the center of this mystery is faced with a difficult decision that will challenge his loyalty to his country and his devotion to his wife.
