The story takes place in Seoul, 2011. Lee Yoon-sung is a talented MIT-graduate who's working on the international communications team at the Blue House. He encounters dangerous situations while solving a variety of cases, both big and small, for people who need his help, and eventually becomes a "city hunter."
On October 9th in 1983, the president of the Republic of Korea is on his way to Aung San Mausoleum in Burma.
Nana gets a few different part time jobs including designated driver service to afford her father's surgery.
Yoon Sung manages to get ahold of the document of the government subsidies for free meals program.
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.
Jin-pyo packs up, having missed his shot, smart enough to send an elevator to random floors while getting in another ? but authorities put a lock on the elevator buttons, meaning that they know he's in there and are preparing for confrontation.
Nana finds herself in a position where she has no where to go, and is being evicted by the new owner of the apartment.
Standing infront of a hotel room, Nana, Yoon Sung, Sae Hee and Young Ju all find themselves in a very misleading and awkward moment.
Nana shoots the man she believes is the city hunter, but without realizing it, she shoots Yoon Sung on the back shoulder.
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.
Both Yoon-sung and Young-ju arrive at the hospital at the same time to verify the victim and its suspects.
Nana rescues Yoon Sung in the National Forensic Service, just seconds before being discovered by Prosecutor Young Joo.
Nana tells Yoon Sung that she's glad he wasn't the one to get shot, and falls unconscious.
With Yoon Sung locked inside the market and Nana standing outside the parking lot, Jin Pyo comes screeching towards her on a motorcycle.
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.
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.
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.
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.
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.
