Xie Xing, a former police elite, was betrayed by his partner of seven years, A Kun, during an operation to capture a drug lord. He was falsely accused of murdering a police officer and a drug dealer, and was unjustly imprisoned in Stanley. He accidentally obtained a chip that contained evidence of the crimes of the high-ranking criminal police officer "Ghost King", and became the target of hunting and wooing by forces inside and outside the prison. In a crisis-ridden prison, Xie Xing relies on his strong skills and calm mind to deal with gang leaders, black police jailers, and revenge forces. He meets allies such as Uncle Wen, Lai Zhong, and Lin Shufen, and gradually uncovers a shocking conspiracy: A Kun was exploited by the ghost king because of his father's old grudge. The real culprit who blamed his master and killed his colleagues was the ghost king Cheng Xiaotian. He secretly sent the chip for decryption, and finally discovered that the "killed" police officer was an undercover ghost king who faked his death. Xie Xing uses prison as a battlefield and the truth as a weapon, vowing to overturn the shady curtain of black and white collusion, wash away grievances, and make betrayers and criminal policemen pay the price.
