However, when his punches meet with suspects before words, he can be a bit of a headache to his comrades. Starting from the age of twenty, Han Sun Mi is the youngest to have passed the bar exam, obtain a doctorate in criminal psychology, and become a senior superintendent in the police force. Having solved five cold cases that even a detective with supernatural powers couldn't do, she is a genius profiler. She has a secret that drives her to do what she does. These two highly-skilled professionals meet their match—a serial killer with abilities that transcend theirs combined. It's going to be a fight worth watching.
