'Signal 2' set for Dec. 7 premiere as Jo Jin-woong's final work

tvN drama series "Signal 2" will begin airing Dec. 7, according to reports.

The show, also titled "The Second Signal," has been confirmed for a Monday-Tuesday time slot starting Dec. 7, a week later than its originally planned Nov. 30 premiere. The first two episodes will air together as a special double broadcast on Dec. 7, with one episode per week from Dec. 8 onward.

"The Second Signal" had been one of the most anticipated titles marking tvN's 20th anniversary. Filming wrapped in August last year, but the broadcast was canceled in December of the same year after Jo Jin-woong's past juvenile criminal record became public. A release was briefly discussed in June but did not materialize.

"Signal" is a mystery thriller in which detectives in the present and the past connect through a walkie-talkie to unravel long-unsolved cold cases. The series stars Lee Je-hoon, Kim Hye-soo and Jo Jin-woong, with a script by Kim Eun-hee and direction by Ahn Tae-jin.
