Shi Dongchu, chairman of the Golden Gate Group and a big shot in the Tiger faction, dies in a car accident, sending shockwaves through both the underworld and the legitimate world. To stop the Golden Gate Group from expanding its influence in legitimate circles and growing even stronger, the police quickly propose “New World,” a plan to intervene in the election of the group's next leader. A fierce power struggle over the chairmanship breaks out between Ding Qing, the group's third-ranking figure of overseas Chinese descent, and executive director Lee Jung-gu, its fourth-ranking figure. With danger closing in from all sides, Section Chief Kang of the police orders Lee Ja-sung, who has been undercover for eight years, to influence the election's outcome. Ja-sung met Ding Qing six years ago and earned his respect and trust. Already sick of life in the underworld, Ja-sung has no choice but to obey. In doing so, he throws himself into a perilous whirlpool of crime.
