In "Signal" Son Hyun Joo appeared again in "Signal" with a strong presence.
On the 11th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 26th, Cha Soo Hyun (played by Kim Hye Soo) the In Joo womens high school incident from 1999 was shown.
In 1999, Kim Beom Joo (played by Jang Hyun Sung) was connected with the grand theft incident and met up with the politician Jang Young Chul (played by Son Hyun Joo). Jang Young Chul said, "We're going to get stricter. If you don't want the organization to go badly so you must keep getting new people."
At this, Beom Joo was kneeling and said, "Just give me anything. I'll be very loyal to you." However, Young Chul said, "What are you talking about. You are going to be loyal to me? You can't do that. Police officers shouldn't be like that."
Meanwhile, "Signal" is about two detectives - one from the past and one from the present who communicate through walkie talkies to resolve long-time unresolved cases.
