On this day, Park Hae Young called Lee Jae Han who was in despair. He said, "The culprit of the Kyeonggi serial murder incident is caught" and informed him that the incident had been resolved.
At this, Lee Jae Han said, "How did you catch him? Do you have evidence?" In addition, he was curious saying, "What? Where is he?"
Nonetheless, Park Hae Young said, "It can't be then. Even if you had found it, the scientific technology of the era doesn't make it possible for this to happen. Nonetheless, we have evidence thanks to you, officer. Even if we have all the scientific technology in the world, if it wasn't for your evidence, we wouldn't be able to catch the culprit. Thank you for allowing us to catch the culprit. Even though it's late."
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.
