Dark Night Tracking

On a rainy night, a body fell from the police station building and hit the police car at the door. The deceased was clutching half of a police badge - number 073156 - belonging to veteran detective Zhou Guodong who died in the line of duty five years ago. Interpol captain Lu Yuan suppressed his inner turmoil and launched an investigation secretly. Forensic doctor Su Qing found a note from the deceased's stomach during the autopsy. There were only three words on it: Night Owl is not dead. "Night Owl" is an underground criminal organization that was officially declared destroyed five years ago. Now it's back with a vengeance and has planted a mole inside the police station. Lu Yuan's partner Uncle Wang, the deputy director, and even the people he trusts most may all be pawns in the darkness. From the money laundering center in the underground bar to the life-and-death fight on the sea-crossing bridge, from the hypocritical masks at the charity dinner to the ultimate showdown on the top of the TV tower - every time you get closer to the truth, it is a collapse of trust. When the mastermind finally surfaced, Lu Yuan discovered that his biggest enemy had always been standing by his side. In the dark night, who holds the candle and walks forward?
