Dong Baek has an extraordinary ability. He can peer into the memories of whoever he touches. With his supernatural power, get it done attitude, and eye-pleasing looks, he is fervently revered worldwide as a superstar detective. 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. Adapted from the webtoon of the same name by Jae Hoo.
