Synopsis

Sano Shogo (Sasaki Kuranosuke), a detective in the Tokyo Metropolitan Police Department’s First Investigative Division, is a lone wolf investigator who will stop at nothing to catch a criminal. The sudden disappearance of his ex-wife three years ago has left a deep emotional scar within him.
 
When the body of a neurosurgeon is discovered in an underground parking lot in Tokyo, with four knives stabbed into the victim’s throat, Sano launches an investigation alongside his partner, Hazumi Anna, and Kanzaki Toru, a researcher from the National Research Institute of Police Science.
