Criminal Investigation: Hunting Down the Killer

Newly assigned to the criminal investigation unit, grassroots detective Lu Chen is immediately thrown into a body-dumping case on a rainy night. There are no fingerprints or witnesses at the scene, only a blurry shoeprint, and the method bears an uncanny resemblance to an unsolved case from three years ago. As the investigation deepens, he discovers that the victim was connected to a secretive organization. Even more disturbing are the mole on his team, altered case files, and witnesses suddenly changing their stories. Layer upon layer of fog closes in, driving him to the brink.
