What is the plot of Inspector Koo?

Koo Kyung Yi, an insurance investigator, is frighteningly intelligent who loves to solve cold cases simply for the thrill of cracking the case, rather than helping to bring justice to the world. Her biggest challenge lays ahead of her when an equally intelligent college student begins their serial killer plot in an accidental murder case in order to defraud her insurance money.


Who are the cast members of Inspector Koo?

The main and supporting cast members have been confirmed for Inspector Koo:

Role Cast Member Where Have I Seen/Heard Them Before?
Koo Kyung Yi Lee Young Ae Jewel in the Palace | Saimdang, Light’s Diary | Wave
Song Yi Kyung Kim Hye Joon Kingdom | Green Fever | Sinkhole
Keon Wook Lee Hong Nae The Uncanny Counter | The King: Eternal Monarch | Catch the Ghost
Santa Baek Sung Chul How to be Thirty | The Witch’s Diner
Oh Kyung Soo Jo Hyun Chul D.P. | Hotel Del Luna | Romance in Seoul
TBA Kwak Sun Young Hospital Playlist | V.I.P | Encounter
TBA Kim Hae Sook Mother of Mine | Room No. 9 | Whisper

Fans of Kingdom should instantly recognize actress Kim Hye Joon, who portrayed the Queen in the zombie horror. Cold and calculating, there are arguably fewer actresses that can pull off the role of a frozen-hearted serial killer.

How will Inspector Koo fare in the ratings?

The very best of the South Korean dramas typically air in the coveted Saturday and Sunday time slots. This means that Inspector Koo has a fantastic chance at earning a big draw in the ratings, and is a potential contender to enter the top ten Korean cable dramas.

In order to enter the top ten, it will need to beat the tvN drama Vincenzo, which has a respectable rating of 14.636%.
