It turned out that Cha Soo Hyun had almost been the third victim of the serial murderer of Hong Won Dong in 1997 but had escaped, as this was a traumatic experience for her.
Afterwards, Cha Soo Hyun thought that the person stopped murders. That wasn't true.After the first body was found, there were nine more bodies that were found in the mountains.
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.
