In "Signal" Jo Jin Woong's tears made the viewers cry too.
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 collaborated with Lee Jae Han (played by Jo Jin Woong) of 1989 and caught the real culprit of the Kyeonggi serial murder incident.
Park Hae Young found out who the real culprit was. The murderer was the driver of bus 95 Lee Chun Goo's son Lee Jin Hyung. Cha Soo Hyun (played by Kim Hye Soo) went to the hospital where Lee Chun Goo was and even had a fist fight with Lee Jin Hyung.
This led to a false confession. Lee Chun Goo had confessed to committing the murder instead of his son. He had actually copied the past murder and in 2015, he had murdered the witness of the first murder. This wrongful love blocked the investigation. In addition, through the walkie talkie it turned out that Kim Won Kyung (played by Lee Shi Ah) became the 9th victim.
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.
