In “Signal” Lee Je Hoon started to reinvestigate the death of the brother Park Sun Woo.
On the 14th episode of tvN Friday/Saturday drama “Signal” (script Kim Eun Hee, director Kim Won Suk) broadcast on Mar. 5 th , Park Hye Young (played by Lee Je Hoon) realized that the incident that Ahn Chi Soo (played by Jung Hye Kyun) was investigating was not the In Joo incident.
On this day, Park Hye Young went to the friend who had falsely testified against his brother Park Sun Woo. That friend got frustrated with Park Hye Young why he’s starting up again on the investigation and said that a couple days ago, Ahn Chi Soo had come to him.
Ahn Chi Soo wanted to ask this friend to testify about the red scarf that would be the decisive piece of evidence to catch the true culprit of the incident.
More than that, Park Hye Young understood that Ahn Chi Soo went to the In Joo police station to find information that’s not about the In Joo incident but about the death of Park Hye Young’s brother. With that, he felt instinctively that there was another secret that was surrounding the death of his brother.
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.
