City Hunter

On October 9th in 1983, the president of the Republic of Korea is on his way to Aung San Mausoleum in Burma. When many people including the cabinet members and the guards are waiting for the president, a sudden explosion takes place at the place. As it turns out North Korea was behind the terror attack, five men in the high-ranking positions in Korea make a decision to retaliate against the North.

Nana gets a few different part time jobs including designated driver service to afford her father's surgery. After she happens to drive Yoon Sung's car, Nana runs into him again in the presidential residence where they start to work. Since Nana receives some help from Yoon Sung and owes him, she insists to pay him back while Yoon Sung simply refuses it.

Yoon Sung manages to get ahold of the document of the government subsidies for free meals program. He tries to resolve the problem and punish Representative Lee his own way. Meanwhile, Young Joo receives a package including the evidence that shows the truth about the corruption case of Representative Lee.

Yoon Sung and Jin Pyo are in confrontation with each other over the way to punish the five men. Jin Pyo suggests that one who finds the next subject first decides how to take revenge. Yoon Sung gets confused after seeing her mother without telling her that he's her son. Nana tries to cheer him up as she understands well how it feels like when not having a mother.

Yoon-sung pulls Nana out of the rifle's scope just a second before the bullet shatters the glass, barely missing her. Yoon-sung slips away while it's still dark, but leaves behind his bullet necklace. In the aftermath, Nana picks it up and tucks it away. Yoon-sung races for the next-door building while the SWAT team moves in on the scene.

Nana finds herself in a position where she has no where to go, and is being evicted by the new owner of the apartment. Soon enough, she finds out that Yoon Sung bought her apartment without her knowing. She is furious and demands to know why he did it and for what reasons. Yoon Sung tries to tell her that she can continue living there.

Standing in front of a hotel room, Nana, Yoon Sung, Sae Hee and Young Ju all find themselves in a very misleading and awkward moment. Yoon Sung knows exactly what everyone's thinking, and while Sae Hee does too, she's perfectly calm about it. With her ex ,Young Ju seething in front of her, she excuses herself, still angry at him for ditching her for his work.

Nana shoots the man she believes is the city hunter, but without realizing it, she shoots Yoon Sung on the back shoulder. As soon as the bullet hits him, he hovers over the ledge, breathing hard and struggles to jump. He jumps off, leaving Seo Yong Hak behind, and Nana takes of running towards him.

After taking Candidate Seo as hostage, Jin-pyo proceeds to take all but one bullet out of his gun and plays Russian Roulette, demanding to know the names of the others involved in the '83 incident. Seo suspected as much, and quickly agrees to give up the other names of the Big Five, if he gets taken somewhere safe. Jin-pyo tells him that he's rotted to the core, for so easily selling them out.

Both Yoon-sung and Young-ju arrive at the hospital at the same time. The prosecutor confirms Lee Kyung-wan's dead body, while Yoon-sung spots his father glowering at him, still dressed up as a doctor, and heads out. Yoon-sung understands that Dad is going to kill Target No. 3, Kim Jong-shik, as soon as the man returns to Korea from his business trip.

Nana rescues Yoon Sung in the National Forensic Service, just seconds before being discovered by Prosecutor Young Joo. Instinctively, Yoon Sung pulls out a knife and holds it at his assailant's throat, only to come eye to eye with Nana. Without a word he sneaks her out carefully amidst the chaos outside, and they ride on one of the outbound ambulances.

Nana tells Yoon Sung that she's glad he wasn't the one to get shot, and falls unconscious. Yoon Sung holds her tight, crying. Shortly, they arrive at Sae Hee's animal clinic where Sae Hee answers the door and quickly takes them in. Without batting an eye, she immediately locks the door and tells ahjusshi to close the blinds. Sae-hee sees the wound and is baffled at the sight of another wound.

With Yoon Sung locked inside the market and Nana standing outside the parking lot, Jin Pyo comes screeching towards her on a motorcycle. Yoon Sung sees his face, acts quickly and shatters the glass door to get Nana first. He knocks her out of Jin Pyo's way and puts himself in between his father and Nana. Jin Pyo knows he lost his advantage and leaves.

Caught between certain downfall and death, Kim Jong-shik lets go of the railing and falls to the highway below, hitting a car windshield and landing on concrete. Young-ju looks up and sees the City Hunter at the railing. Yoon-sung is shocked. Jin-pyo calls to ask sternly why Yoon-sung would start his revenge only to turn back to save the guy.

Yoon Sung rescues Young Joo from being gassed to death, and pulls him out of the car in time just as he's lost consciousness. He stirs awake and reaches out to grab Yoon Sung's ankle, and tries to make out the silhouette. Yoon Sung stops, and then turns towards him, just as Young Joo loses consciousness again. He calls the police to report a man lying on the ground and leaves.

Young Joo's use of Yoon Sung's Thai name stops the latter in his tracks. He doesn't expressly deny Young Joo's assertion, just evades it by telling him to bring proof if he's so sure he's the City Hunter. Young Joo vows to catch him in the act. Yoon Sung maintains his composure until he's out of sight, then collapses, weakened from the toxic exposure.

President Choi walks up and hands Yoon Sung the volume that he's looking for, containing his father's picture from his days as a secret service agent. Yoon Sung quickly covers up his interest in the book and says he was just browsing at random. The president asks for some help uploading a picture onto his blog.

Jin Pyo gets ambushed at home by eight of Chun's minions, a number too large to fend off single-handedly even for a man like himself. Yoon Sung quickly fights his way to Jin Pyo's side, and the men stand back-to-back as the gang encircles them. Chun Jae Man's assistant quickly picks up on the fact that Yoon Sung was City Hunter all this time.

Young Ju manages to stop the City Hunter and then pulls a gun on him. Yoon Sung immediately swipes the gun and turns it right around on him. But the prosecutor doesn't even flinch as he inches forward, head to barrel. He uses this one chance to unmask the City Hunter and he finally gets his confirmation, as Yoon Sung stands there looking back at him, gun still trained at Young Ju's head.

Beaten to a bloody pulp by Chun Jae-man's minions, Young Ju dies. In the meantime, Kim Jong Shik wakes up in his hospital bed. Yoon Sung takes Young Ju's phone, and sees the text message supposedly sent from the City Hunter that directed him to the junkyard. He asks Jin Pyo why he did it, and Jin Pyo replies that all he was doing was sending the prosecutor to find the truth.
