"A series of bizarre murders is occuring in the city and it's up to the High-degree Murder Division (HMD) to find the culprit. The string of crimes seems to match the pattern of an assassin who was responsible for the deaths of several government officials years ago. The only problem? That man was shot to death by one of the HMD's own officers. So then who is responsible for the ongoing murder spree? The HMD must find out, and quickly, before the killer strikes again."
