Storyline

When a serial killer strikes women who all have a similar appearance, the police department's Special Crime Investigation Team is stumped. While Cha Ji An (Jang Na Ra), an elite detective, and her fellow colleagues are assessing the latest crime scene, the mysterious Lee Hyun (Seo In Guk) shows up and instantly assesses the trademark attributes of the killer. Hyun is a genius criminal profiler with a degree in criminal psychology who received an anonymous email that brought him to the crime scene all the way from the United States. The serial killer seems to be sending a personal message to Hyun with the clues he leaves behind, and Hyun wonders if it could be related to an escaped criminal "monster" from his childhood who killed his father and was responsible for the disappearance of his younger brother.

very good
5 January 2017 | by See all my reviews

Better than Dexter, who was, in my opinion, too long, too exaggerate, too creepy. Better than the Mentalist - too long, too exaggerate, too bloody. 16 episodes were just perfect for me. I mean: when I realized who the little brother was, the script revealed it, too. When I realized who the serial killer was, the script revealed it, too. Not like: "Gosh, I'm so smart! How come the others didn't seen it!" Genial. But the plot goes on. So are the surprises. Worth to see it. The love-story is left on the background, and this was perfect for me. And the female police officer was very smart and very efficient. Her colleagues, too. All of them.
