My name is Chen Nianan. I inherit the spirit of three generations of police officers and am determined to eradicate the Jiangcheng Tiger Shark Group. In my previous life, I trusted my mole Li Jianjun and was framed by him together with the evil forces. I died unjustly on charges of murder, collusion and other crimes. Before execution, my grandfather's undercover police badge suddenly shone brightly, bringing me back to the turning point of my fate.
After resurrecting my life, I restrained my sharpness, took steps step by step, and relied on my past life memories to predict cases and avoid traps. I went from tit-for-tat to fighting side by side with Su Qinghan, the forensic doctor who was responsible for my brother's unjust case. We went deep into the Tiger Shark Group to track down smuggling and contraband products and uncovered layers of protection. This time, I want to destroy the criminal group, eliminate the cancer in the police force, bring justice to my grandfather and all the victims, and let the light of the police badge illuminate every darkness in Jiangcheng.
