While under arrest for insubordination, sniper Kim Seol-woo gets recruited by the intelligence agency. Meanwhile, Yeo Woon-gwang rises to stardom.
Neither Woon-gwang nor his chief celeb manager Cha Do-ha likes his new bodyguard. If they can't make him leave, they'll just make him want to leave.
After learning Woon-gwang has been involved in a similar accident before, Seol-woo relays his suspicions to Lee Dong-hyun, his comrade and mentor.
From Chairman Victor's private collection of precious cultural artifacts, a wood carving catches Seol-woo's eye. Then, the power suddenly goes out.
For his next task, Seol-woo must get close to Do-ha, but it isn't so easy when she has forbidden him to approach her within a 1-meter radius.
Seol-woo gets drunk and sends cute text messages, all in the name of his mission. Meanwhile, Congressman Baek tries to make a deal with Jang Tae-ho.
To stop Seol-woo from blowing his cover, Dong-hyun tells him to stay out of the investigation. However, Seol-woo continues his search for the culprit.
Do-ha asks to hear the truth directly from Seol-woo. Meanwhile, Dong-hyun and Seol-woo begin preparation for their next mission, the Black Auction.
For the country and Do-ha's father, Un-kwang decides to help Seol-woo. Do-ha, not able to trust Seol-woo, requires him to sign a contract.
Seol-woo secretly meets with Jang Tae-ho to hand over a crucial piece of evidence regarding Robert Yoon's death and to discuss the third wood carving.
Jang Tae-ho lays down his conditions to Mo Seung-jae. For their new mission to commence, Seol-woo and Do-ha must first get the approval of Un-kwang.
Seol-woo doesn't pick up Do-ha's phone calls, so she decides to check his workroom. Dong-hyun visits Jang Tae-ho and asks if he knows where K is.
All sides involved, including Lee Dong-hyun, Mo Seung-jae and the National Intelligence Service, are continuing the search for the missing videotapes.
Jang Tae-ho and Lee Dong-hyun discuss Song Mi-eun and her past: She decided to marry Mo Seung-jae, not for his wealth but for her own survival.
The police find the vehicle involved in the hit-and-run accident. Determined to kill off the bad guys, Seol-woo gets his gun from his workroom.
For Seol-woo, it's finally time for revenge. For all involved, it's finally time for closure and for punishments to be given where they are due.
