Medical Examiner Geun Namkyu is fresh out of school and has just closed his tenth case. Suddenly his brother goes missing and while the police look for him, the abductor is sending Namkyu pieces of him.

He is trying to keep it together but it is getting beyond difficult when every single one of the cases that lands on Namkyu 's table has a piece of Jinyoung's body.

Detective Lee does his absolute best to find the killer that is messing up his station before a lot of people end up dead but every time he gets a clue , he meets a dead end. Worst of all the clues lead to Geun Namkyu

The question becomes is the killer causing a distraction so they can finish their puzzle of body parts or are they trying to send a message
