A secret factory in North Korea has a counterfeit system of more than 99% for the US dollar. Cha Ki-sung, the head of the North Korean special forces, lost his wife in the previous operation, and was dissatisfied with the country. He decided to lead a group of men to escape from North Korea. And before leaving, he wanted to steal the factory's most valuable counterfeit banknote templates. Lin Zheling (played by Hyun Bin), the leader of an action team under Cha Ki-jung, led his team members and had a fierce exchange of fire with Cha Ki-jung's gang. In the end, except for Lin Zheling, all the other workers and security personnel were killed, including Lin Zheling's wife. The high-level military and political leaders of North Korea ordered that the counterfeit banknote templates must be recovered, and Lin Zheling was determined to hunt down Che Ki-jung to the ends of the earth to avenge his wife. The North Korean intelligence department received intelligence that after Che Ki-jung fled, he traveled through several cities in China and finally fled to Seoul, South Korea. Taking advantage of the high-level talks between the North and the South, the high-level military leaders of North Korea took Lin Zheling to Seoul as an attendant and notified the South Korean police to launch a joint operation to capture Che Ki-jung together. The South Korean police knew nothing about Cha Ki-jung's true identity and the actual purpose of the North Korean authorities, so they sent a soy sauce criminal policeman, Kang Jin-tae (played by Yoo Hae-jin), to assist Lin Zheling, but in fact he was perfunctory and monitored the North Korean actions. At this time, Cha Ki-jung and his former North Korean special forces subordinates had all smuggled to Seoul. The enemy was strong and we were weak, and the seemingly impossible cooperation operation began. @秀山鲤鱼
