In "Signal" Jo Jin Woong's real culprit ended up stopping the continuous crimes.
On the 4th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Jan. 30th, the long term unsolved murder mystery team worked hard to find the truly guilty person that was responsible for the Kyeonggi serial murder that had happened in 2015.
In 2015, Lee Chun Goo was caught and said that his son had already paid for his crime. In 1989, Lee Jae Han (played by Jo Jin Woong) had been suspicious of Lee Chun Goo and had gone into his house. With that, he had found Lee Chun Goo's son.
Lee Jae Han looked for Lee Chun Goo's son Lee Jin Hyung and abused him. At that time, Lee Chun Goo hit Lee Jae Han's head. Lee Chun Goo said, 'Not my son. Over my dead body. Not my son."
Lee Jae Han said, "He will commit murder again. There's no witness and no evidence so I will end this myself" and raised the gun. Lee Jin Hyung who was going to avoid this was about to fall from the rooftop. He caught Lee Jae Han, but Lee Jae Han smiled in a sly way and let go of Lee Jae Han's hands.
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.
