Seo Jeong-hu, aka Healer, is one of the best in the "courier" business. His next job should be simple – or so says his hacker partner, Ms. Jo.

Healer's attempt to get a sample for DNA testing leads to a scary encounter for Yeong-sin. Later, Mun-ho gets a call from the DNA lab.

Healer decides to spy on Yeong-sin for clues about who framed him but discovers that someone else is secretly watching her as well.

When Ms. Jo opposes his plans to go undercover, Healer assures her that it won't take long. Yeong-sin tries to convince her boss to publish her story.

Mun-ho mentions Ji-an to Myeong-hui and ends up confronting Mun-sik. Fearing that Bae Sang-su may catch him, Ms. Jo tells Healer to avoid Yeong-sin.

By manipulating the media, Mun-sik turns Joo Yeon-hui's case on its head. Feeling lost with no other options, Yeong-sin calls Mun-ho for help.

Mun-sik orders a background check on Yeong-sin to see if she was adopted. Mun-ho tasks Bong-su with uncovering Hwang Je-guk's licentious private life.

Shocked to see an email notification for Mun-ho sent from Healer, Yeong-sin interrogates Mun-ho about his relationship with Healer.

Mun-ho threatens to tell Myeong-hui everything if something happens to Ji-an again. Mun-sik is running out of time to turn in Ko Seong-cheol's killer.

At Someday News, everyone eagerly awaits Yeong-sin's reporting. Mun-sik and Boss watch the live broadcast of Kim Ui-chan's candidacy announcement.

Back home from work, Mun-ho discovers that there’s been an intruder and receives a call from a restricted number asking about what happened in 1992.

Mun-ho is furious at his brother for coming to visit Someday News. Jeong-hu meets one of his father's close friends.

Bae Sang-su is confident that he has finally caught Healer. Mun-sik arrives at the Double S Guard's headquarters to meet the man they brought in.

Ms. Jo tries to hack into the police server to obtain Yeong-jae's statement. Yeong-sin gets worried when Bong-su becomes unreachable.

Jeong-hu follows a lead given by Mun-ho to find the truth behind his father's case. Ms. Jo notices something off about Yeong-sin's location tracker.

Yeong-sin's stunned face replays in Jeong-hu's mind, but he tries to focus on getting his father's statement. Yeong-sin visits Myeong-hui at home.

Jeong-hu confronts Boss. Fearing for Jeong-hu's safety, Yeong-sin tries to follow him inside. Mun-ho airs the content of the audiotape on live news.

Tracking the location of Mun-ho's phone, Jeong-hu arrives at Someday to find that no one’s there. Mun-ho's phone rings, but the caller ID is blocked.

Jeong-hu resorts to plan B when he hits roadblocks trying to prove his innocence and the people closest to him come under attack.
