In "Signal" Lee Je Hoon and Jo Jin Woong took control of the murderer son and his father.
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) of 2015 and Lee Jae Han (played by Jo Jin Woong) of 1989 caught the real culprit of the Kyeonggi serial murder incident.
In this process, Park Hae Young found the true culprit. This was the son of the bus driver Lee Chun Goo who had been the driver of bus 95. Cha Soo Hyun (played by Kim Hye Soo) went to the hospital and there, there was a physical brawl with Lee Jin Hyung.
Nonetheless, the situation had reversed as there was a false confession that the bus driver had made. The current Lee Chun Goo had confessed that he was the murderer. He had copied the past murder and had even murdered the witness. Nonetheless, it turned out that the evidence showed that Lee Jin Hung was the true murderer. Cha Soo Hyun went to the press release scene where Lee Jin Hyung was declared to be the murderer and was arrested.
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.
