Mission: Possible

The Chinese MSS receives vital information about an illegal supply of firearms from China to Korea where they send a rookie officer named Wong Iring to investigate and capture the smugglers. Iring's next plan is to infiltrate Korea as Yoo Da-Hee and meet a Korean special operative but ends up meeting a detective and former special forces soldier named Woo Soo-Han. Da-Hee tells Soo-Han about the mission and presents the target SI Chem Park Du-Sik, a rare-earth element importer from China, who is actually involved in arms smuggling. The duo follows Du-Sik to a cafè in Gangnam.

After a topsy-turvy ball dance, the duo manages to acquire his phone, only to find it is a flip phone. After keeping the phone back, Du-Sik receives a call and while chatting with someone, he gets killed with a dart and his death has been faked as a heart attack. The next day, Soo-Han and Da-Hee receive the news about the Rodeo mob boss has been shot while leaving his club. After interrogating a fortune teller advised by Soo-Han, the duo head to meet Rodeo boss rival Axe Clan where they meet the clan's boss, but are soon attacked by masked men. Soo-Han and Da-Hee escape, but not before retrieving the clan's boss's phone.

With the help of a hacker, the duo reaches the person's address where they find the person dead and deduce that he had been killed 3 days ago. The duo learns about the person's identity as Kim Yeong-Gu, the security head of Mugwang International and also learns about its execs Director Jeon-Hoon. Soo-Han remembers that Jeon-Hoon was the one who threatened Du-Sik after he had checked his phone. The duo learns that a party is held at Alvin Hotel the next day. Soo-Han and Da-Hee leave for the party. Despite knowing that Jeon-Hoon is their boss's killer, the Axe Clan makes an arms deal to sell arms at midnight. Soo-Han and Da-Hee are exposed where they are captured and brought to Jeon-Hoon, who orders Soo-Han to kill cops at a local police station in exchange for Da-Hee's life.

Soo-Han is escorted to the police station, but he injures Jeon-Hoon's men and reaches back to the hotel, only to find that Da-Hee is escorted somewhere. The cops arrest Soo-Han, and he is visited by the NIS, who learns about Da-Hee's real identity and that she is sent as a 'sacrifice' to die in the mission. Soo-Han escapes from the station and reaches the hideout where the deal between Jeon-Hoon and the Axe Clan is headed. Soo-Han frees Da-Hee and kills Xia-rong, one of the assassins Da-rong's brothers, which alerts the gangsters and they head to kill the duo. Soo-Han and Da-Hee manage to kill/arrest all the gangsters including Da-rong and Jeon-Hoon.

Later, Soo-Han gets arrested but is offered a deal by the NIS and MSS to become a secret agent in exchange for his release. Soo-Han agrees, and he, along with Da-Hee are sent to Russia for their next mission.
