Through the Darkness

In 1990s Seoul, a mysterious killer known as 'Red Cap' terrorizes the city with brutal, random attacks on women, leaving detectives powerless. To catch him, Kook Yeong Su, head of the Criminal Behavioral Analysis team, recruits former detective Song Ha Yeong, a perceptive but reserved individual, to apply criminal profiling techniques. While skeptical, homicide expert Yun Tae Gu and her team must learn to trust this new method to solve the case. As Song navigates the challenges of understanding criminals, he must also confront the emotional toll of his work. ~~ Adapted from the autobiography "Through the Darkness" (악의 마음을 읽는 자들) written by Korea's first criminal profiler Kwon Il Yong and journalist-turned-author Ko Na Mu, depicting some of Kwon's field experiences.
