In "Signal" Kim Hye Soo thought back to very important details of the past.
On the 9th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 20th, Park Hye Young (played by Lee Je Hoon) found out the identity of the last disappeared person in the serial murder incident of Hong Won Dong.
On this day, Park Hye Young learned that the last person was Yoo Seung Yeon who had worked at a lightbulb company. Among the items in Yoo Seung Yeon's possession, Hye Young found an accounting book and learned that she had often used a convenience store. Hye Young told this to Cha Soo Hyun (played by Kim Hye Soo) right away.
Soo Hyun was going to go to Hye Young and that moment, she started to think back to where the telephone poles were and remembered that she had started to walk in the opposite direction.
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.
