"IRIS 2" Lee Beom Soo officially begins working with Mr. Black.

During the 14th episode of the KBS drama "IRIS 2", Yoo Joong Won (Lee Beom Soo) receives his very first assignment from Mr. Black. Yoo Joong Won then learns about the location of the Catholic Church where Ji Soo Yeon's (Lee Da Hae) older brother stays as a priest.

While handing over NSS prisoners Ray (David McInnis) and Lee Su Jin (Yoon Joo Hee) to IRIS, Ray is murdered by Jung Yoo Gun (Jang Hyuk) when he attempts to run away. Mr. Black orders Yoo Joong Won names him the team leader of IRIS.

If Yoo Joong Won finds out the locations of the atomic weapons from Baek San (Kim Young Chul), he will be able to finally return to North Korea with Kwon Young Choon (Ahn Seung Hoon) as he wishes.

Yoo Joong Won's desire to take revenge on Jung Yoo Gun becomes stronger and stronger as he keeps working for IRIS. The personal war between Yoo Joong Won and Jung Yoo Gun is predicted to intensify in the episodes to come.

Meanwhile, this episode also featured Baek San revealing the secret location of the atomic weapons to Choi Min (Oh Yeon Su). However, there are only 4 weapons at the location. Baek San tells Choi Min that he is planning to use the fifth one as bait to bring IRIS down.
