"IRIS 2" Jang Hyuk and Kim Young Chul finally meet again.

March 20, the 11th episode of the KBS drama "IRIS 2" featured IRIS using Jung Yoo Gun (Jang Hyuk) as prisoner in order to make a deal with the NSS.

IRIS says, "We will trade Jung Yoo Gun and Baek San (Kim Young Chul) at the time and place that was previously mentioned" and "If you agree to the trade, we will stop all of the terror acts in Hanbando."

Later, Ji Soo Yeon (Lee Da Hae) learns that Baek San is actually Jung Yoo Gun's biological father. As soon as she finds out, she tells Baek San the truth.

Baek San says, "If you tell me everything he told you, I'll agree to the trade. But you have to do it as I say" and begins to cry.

However, Jung Yoo Gun still doesn't know that Baek San and Yoo Sang Joon are the same person. Jung Yoo Gun still believes Baek San is the person who murdered his father.

At the end of the episode, Baek San and Jung Yoo Gun meet and build up the anticipation. Baek San knows that Jung Yoo Gun is his biological son while Jung Yoo Gun has no idea. What kind of changes will happen in the future?
