Kim Eun-hee channels these tragedies into a gripping narrative that reminds viewers: complete crimes donโt exist, and truth always finds a way to surface.
The story revolves around three detectives connected across time through a mysterious walkie-talkie. Lee Jae-han (Jo Jin-woong) investigates crimes in the 1980s and 90s, while Park Hae-young (Lee Je-hoon), a profiler in the 2010s, receives transmissions from the past. Detective Cha Soo-hyun (Kim Hye-soo) bridges both timelines, and together they reopen cold cases and uncover truths long buried, delivering a message of hope to victims and their families: justice delayed is not justice denied.
Each episode draws from real Korean criminal cases, including the kidnapping and murder of Park Chorong Chorong Bitnari, the collapse of Seongsu Bridge, and the infamous serial thefts by Jo Se-hyung. These dramatized events lend authenticity and emotional weight to the series, making it more than just fiction itโs a social commentary. Despite airing on cable, Signal achieved massive popularity thanks to Kim Eun-heeโs masterful writing and the showโs intense emotional pull. With Season 2 confirmed for release in 2026 and currently in production, anticipation is high. In a country where drama sequels are rare, Signalโs continuation speaks volumes about its cultural impact. Its core message remains timeless: โEven if time passes, the truth stays where it is. If we donโt forget and keep searching, it will be found.โ

โOriginally composed by Shin Jung-hyeon and performed by Jang Hyun (1972) and Seo Yoo-seok (1973), this song was remade and featured in the opening sequence.
๐ฑ This song was remade as part of the dramaโs OST, and the contrast between its original historical context and the unique tone of singer Jung Cha-sikโs modern rendition evokes a subtle echo of the dramaโs central themeโtime travel.”
