Confidential Assignment

Confidential Assignment is a 2017 South Korean action comedy film directed by Kim Sung-hoon. It stars Hyun Bin, Yoo Hae-jin and Kim Joo-hyuk. In the film, a North Korean officer and a Seoul detective team up to track down a dangerous fugitive, who is running a gang of counterfeiters. Plot Im Cheol-ryung, an officer of a special investigation team in North Korea, barges into a warehouse that prints counterfeit money, where he learns that his superior Cha Ki-seong and his own team are there to steal the master plates to print the counterfeit money. A shootout ensues where Cheol-ryung's wife Hwa-ryung and his team are killed, while Cheol-ryung is gravely injured. Meanwhile, the North Korean officials learn that Cha Ki-seong has fled to South Korea, where Cheol-ryung is ordered to capture Ki-seong and retrieve the stolen master plates, and is given only three days to complete his mission. However, South Korean officials suspect that Ki-seong is really a killer, and they assign Detective Kang Jin-tae from Seoul to watch over Cheol-ryung tightly as they suspect he intends to kill Ki-seong for revenge. Jin-tae meets Cheol-ryung at the airport, and they head for Myeong-Dong to check on one of Ki-seong's men, Park Myung-ho, but Cheol-ryong escapes after learning about Jin-tae's mission. Cheol-ryung arrives at Myeong-Dong to Jongro where Jin-tae also arrives there and interrogates Park, but the latter escapes. After the orders from his superior, Jin-tae takes Cheol-ryung to his home to spy on him. Having guessed the Jin-tae's plan, Cheol-ryung removes the SIM card which Jin-tae had inserted in his phone to track his location anytime. The duo learns about the location where Park was supplying drugs and a fight ensues where Cheol-ryung takes the phone of one of the men and gives it to Jin-tae. Cheol-ryung learns Park's location after secretly bugging Jin-tae's phone. The duo heads to the restaurant where they find that Park is conversing with one of Ki-seong's comrades (who had been present at the warehouse). The comrade learns that Park plans to settle in South Korea, where he kills him under Ki-seong's orders. Cheol-ryung arrives and warns Ki-seong of his impending death, where he fights the comrade, who escapes. After checking Park's belongings, the officials learn about Cheol-ryung's mission.
