tvN drama ‘Signal’ is returning with season 2.

tvN announced on the 5th, “The drama ‘Signal’, which was greatly loved by viewers, is returning as ‘The Second Signal.’ We are entering full-scale production with the goal of airing in the first half of next year, which is tvN‘s 20th anniversary.”

‘Signal’, which aired in 2016, is an investigative drama in which detectives from the past and present who are connected by an earnest signal (walkie-talkie) from the past re-examine old unsolved cases. It received favorable reviews for its unique subject matter of solving long-term unsolved cases through a walkie-talkie connecting the past and present, its intense narrative in which the earnestness of a detective from the past and present solves the unsolved case, and its famous line, “The past can change. Don’t give up.” Here, the final episode of ‘Signal’ recorded its own highest viewership rating with an average of 13.4% and a peak of 15%. (Nielsen Korea, paid platform)

‘Second Signal’ (written by Kim Eun-hee and directed by Ahn Tae-jin), scheduled to air in the first half of 2026, will feature the reunion of Kim Hye-soo as long-term unsolved case detective ‘Cha Soo-hyun’, Jo Jin-woong as violent crimes detective ‘Lee Jae-han’, and Lee Je-hoon as long-term unsolved case profiler ‘Park Hae-young’.

Here, writer Kim Eun-hee will continue to write the script for her previous work, and director Ahn Tae-jin, who wrote the script and directed the film ‘Owl’, will take the megaphone, heralding a new revival of a high-quality time-slip investigation drama. In particular, since Season 1 ended with an open ending with the survival of Lee Jae-han, who has been missing for 15 years, attention is focused on what kind of story will unfold in Season 2.

The production team of ‘The Second Signal’ said, “We will make thorough preparations to present an even more fun and in-depth Season 2 in order to repay the love you sent us for Season 1. We ask for your great anticipation and interest in ‘The Second Signal’.”

‘The Second Signal’ will air in the first half of 2026.
