Song Kihyung was in position with her partner, Yeri, as they were trying to catch the members of a drug and sex slave trading gang in Seoul. Currently, they were behind an abandoned storage shed that was suppose to be the gang's place of business.

"Okay," Kihyung says to Yeri, as she loads her gun, "I'm going to need you to stay guard as I go in and find as many gang members as I can. Then, when I give the signal, you come in with the backup cops when they arrive." "Got it," Yeri quietly says. Kihyung turns on her wireless mic and sneaks in. She notices two members of the gang talking as she hides behind a big box.

"Okay," one of the men says, "here what you need to do Chanyeol. After giving to girls and the drugs the order numbers, you are to keep an eye out for the cops, and count the money at the entrance as we start the auction. You got it?" The other man, whom is assumed to be Chanyeol, says, "Yes. Just remember the deal we had, okay Snake?" "Got it," Snake told Chanyeol as he gets ready to leave, "I'm going to get the girls for the show. Start gathering the drugs to put in the truck when BamBam arrives." Chanyeol nods and follows Snake's orders.

Kihyung waits for Chanyeol to be caught off guard when she asks Yeri if backup arrived. When Chanyeol occupies himself, Kihyung says, "R-E-D," the signal, she gets handcuffs in her left hand as she holds the gun with her right hand and says, "Freeze!" Chanyeol drops everything on the ground when he heard that and turns around to see Kihyung and Yeri with other cops. Kihyung handcuffs Chanyeol as he was screaming for his buddies. Two armed men showed up and started fighting.

Using the police training she learned at the academy, Kihyung started to swing and kick the as they came for her. Then Yeri helps out. When one guy was shooting, Kihyung shot him in his arm and side. "Get her!" he said to his partner. As the other cops started to help them out, the other guy tried to kidnap Kihyung, but Yeri hit him with her gun, and the guy took her and used a handkerchief, soaked in alcohol, to knock her out. And when Kihyung tried to save her partner, the guys held a gun to Yeri's head, and said, "One more move, and this pretty lady dies." They soon left with her, and Kihyung and the other police officers took Chanyeol in.

With Yeri gone, Kihyung didn't know what to do. The only thing she has now are the leads on the case, and one of the gang members, Chanyeol. With these, Kihyung is going to do everything in her power to save Kihyung, even if it means risking her life.
