Su Nian, the only daughter of anti-narcotics police officer Su Zhenguo, witnessed her father die in the line of duty in her second year after being admitted to the police academy. At the funeral, she accidentally discovered that she could see her father's ghost and got a key clue - a large number of drugs were transiting through Yunzhou from the southwest within three days.
In order to track down his father's unfinished case, Su Nian trained hard at the police academy. At the same time, he secretly used his ability to talk to dead souls to repeatedly solve old unsolved cases around the campus, attracting the attention of instructors and classmates. The ghost of her father is always by her side, guiding her investigation ideas with the experience of the older generation of drug police officers.
After graduation, Su Nian inherited his father's police number and joined the anti-narcotics detachment, and became a partner with Lu Zheng, his father's apprentice and already a key police officer. The two teamed up to track down the Yunzhou drug trafficking network and found that behind it was a large criminal group covering three provinces. As the investigation deepens, Su Nian discovers that his father's sacrifice was no accident - someone inside leaked operational information.
Su Nian and Lu Zheng established an inseparable trust at the critical moment of life and death, and their relationship heated up as they fought side by side again and again. In the end, she used her psychic ability to locate the inner ghost and guide the police to destroy the drug cartel in one fell swoop. After the dust settled, the police badge inherited by Su Nian remained on the anti-drug frontline forever, and the love between her and Lu Zheng also took root under the police badge.
Purpose: Justice may be late, but it will not be cut off in the blood of the anti-narcotics police. Through the unique setting of the heroine inheriting her father's will and pursuing the murderer side by side with the undead, it shows the sacrifice and inheritance of the unknown heroes on the anti-drug front, and pays tribute to the true power of guarding the light in the darkness.
