——When the police become prey, lies are more deadly than bullets——
Cheng Yan, 28 years old, is the youngest inspector in the police force. He is burdened with an ulterior secret - his father, Cheng Gang, infiltrated the Blue Dragon Society, Asia's largest drug lord organization, as an undercover agent twenty years ago. He disappeared from the world, leaving only a severed hand that was sent back to the police station.
When Zhou Zhen, the new generation leader of the Qinglong Society - a criminal genius as elegant as a scholar and as cruel as an executioner - expanded his drug empire to its peak, Cheng Yan volunteered to take on the task: disguised as a dismissed tainted police officer, and sneak into Zhou Zhen's dark kingdom.
However, Zhou Zhen's "game" is far more dangerous than imagined.
• He tested his loyalty with his life and studied human nature with his scalpel,
• He controls an "impossible to fool" lie detection system,
• He even smiled at Cheng Yan: "You look so much like your father."
This is a gamble with no retreat.
Cheng Yan must survive Zhou Zhen's suspicion, stay awake amid lies, and find the truth about his father's disappearance on the gradually blurring boundary between good and evil - even at the cost of becoming the kind of person he hates most.
"The Sin of Backlight"
— about betrayal, inherited sin, and how a policeman stares at his own reflection on the edge of an abyss.
