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 looks for clues to find out who framed him by spying on Yeong-sin. While doing that, he realises that someone else is secretly watching her as well.

Healer assures Ms Jo when she opposes his plans to go undercover; Yeong-sin struggles to convince her boss to publish her story.

While mentioning Ji-an to Myeong-hui, Mun-ho ends up confronting Mun-sik. Ms Jo tells Healer to avoid Yeong-sin as she fears that Bae Sang-su may catch him.

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.
