Plot

The story follows Kang Kwon-Joo (Lee Ha-Na), the leader of the 112 emergency call center who possesses an extraordinary ability to hear sounds beyond the range of normal human perception. Following the events of the previous seasons and the death of her former partner, she struggles with post-traumatic stress disorder (PTSD) while continuing her duties. The team faces a new threat: a serial killer who also possesses enhanced hearing capabilities, using this advantage to commit murders. To stop the killer, Kang Kwon-Joo collaborates with Derek Cho (Song Seung-Heon), a principled team leader from the Los Angeles Police Department (LAPD) who specializes in dealing with criminal gangs.
