In "Signal" Kim Hye Soo was successful in finding the person who was responsible for the motorcycle accidents.
On the 9th episode of tvN Friday/Saturday drama "Signal" (script Kim Eun Hee, director Kim Won Suk) broadcast on Feb. 19th, Cha Soo Hyun (played by Kim Hye Soo) and Lee Je Han (played by Jo Jin Hoong) started chasing the person who was part of the 'hit and run' patterns on a motorcycle.
On this day, Cha Soo Hyun had found a motorcycle on the street while she was a young detective on the job. The person riding the motorcycle was a person that was being investigated for a series of robberies. She thought that this person was definitely the guilty one and apprehended him.
Cha Soo Hyun had found that this person was the true culprit. All the other coworkers than Lee Je Han clapped, applauding her as a detective.
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.
