Crimes This Horrible Are Better Left Unsolved
Lieutenant Cho (Han Suk-gyu), a cop under investigation for corruption, is put in a charge of investigating a series of seemingly unsolvable grisly murders. Dismembered bodies are being found in garbage bags all over Seoul but the surgically-amputated arms and legs do not match, making the victims almost impossible to identify.
Once Cho discovers that the victims were all romantically involved with one woman, Chae Su-yeon (Shim Eun-ha), she becomes the focal point of the investigation. As his suspicions towards Su-yeon grow, so does his attraction towards her. Will he be able to unlock the secrets buried in her past before it's too late?
