The hit series Signal is set to return with a second season.
The sequel, titled Second Signal (direct translation), is slated for release in the first half of 2026, aligning with tvN’s 20th anniversary celebrations.
The original lead trio ― Kim Hye-soo, Cho Jin-woong and Lee Je-hoon ― will reprise their respective roles Cha Soo-hyun, Lee Jae-han and Park Hae-young, according to tvN.
Along with the returning casts, the series is once again written by Kim Eun-hee, the acclaimed writer behind hit K-dramas such as Kingdom and Sign, and will be directed by An Tae-jin, the filimmaker behind The Night Owl, which won best picture at the 59th Baeksang Arts Award.
First aired in 2016, Signal is a crime thriller that follows detectives from the past and present as they reopen long-unsolved cases, linked by a mysterious radio transmission. The series ended on an open-ended note, revealing the survival of the long-term missing person Lee Jae-han.
Praised for its gripping narrative and unique premise of solving cold cases through a time-transcending walkie-talkie, Signal earned widespread acclaim during its run.
The final episode of Signal recorded its highest viewership ratings, peaking at 15%, according to Nielsen Korea. – The Korea Herald/Asia News Network
