Did You Know?


Some Korean family names, such as Kim, Lee, and Park, are extremely common. Thus, there are numerous characters in the series named "Kim" - the police chief, the sergeant, the lawyer, and others - who are not related to each other. Also, Lee Chang-Joon, the prosecutor, is the son-in-law of Lee Yoon-bum, chairman of the Hanjo Group, but they do not otherwise share a family relationship. See more »


The male lead has undergone insular cortex surgery in his childhood. The insular cortex has many functions including representing emotions, and empathy. Insular cortex surgery is performed for the epilepsy treatment. But hypersensitivity to sounds isn't treated by brain surgery. See more »

Not a single Dull Moment
14 February 2018 | by asthabSee all my reviews

First of all, I loved the background music - its gripping. It a very well written and executed how, with good story line and acting. You wont know anything until the very end, and keep doubting every character.

Its a decently paced show, and you wont find one boring moment - amidst all revelations, blame games and well, causalities! Also gives you a sneakk peak into the power game in South Korea.

Give it a try if you like suspense thrillers. You wont be disappointed!
