Criminal Minds, the tvN crime thriller series, will be back with episode 15 next Wednesday, September 13, at 10.50 pm KST. This chapter will probably revolve around the evil moves of serial killer Kim Yong Cheol, who is popularly known as The Reaper.

The psycho killer seems to be having fun playing around with the lives of highly trained NCI profilers. After killing team leader Kang Ki Hyung's wife, Seo Hye Won, the culprit was imprisoned. Although the news about his prison break shook the team members, they were not expecting him to make any moves against them in the near future.

But The Reaper alerted the NCI profilers by leaving the earrings of Seo Hye Won at a crime site. Then he targeted Kim Hyun Joon and succeeded in sending him behind bars. Now, the NCI team is closely watching all his moves with the help of bubbly tech analyst Nana Hwang.
