In "Signal" Jo Jin Woong went and sought revenge against the Kyeonggi serial murder incident.
On the 4th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Jan. 30th, Park Hae Young (played by Lee Je Hoon) used his profiling skills and was very sure that the real culprit of the Kyeonggi serial murder incident was not Lee Chun Goo (played by Kim Ki Chun) and his son.
On this day, Park Hae Young was investigating Lee Chun Goo and said, "My son paid for his crime on that day. If it wasn't for that crazy man." With that, he started to talk about the policemen Lee Jae Han (played by Jo Jin Woong) who had come to him after the incident.
The facts were this. Park Hae Young had finished the walkie talkie session with Lee Jae Han and went to the house of the driver Lee Chun Goo. After drawing a gun, he found Lee Chun Goo and his son Lee Jin Young. He knew from the bottom of his gut that this was going to be the real culprit.
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.
