A bullet caused Zhou Yun, the captain of the criminal police detachment, to die at the door of the chemical plant on a rainy night.
When he opened his eyes again, he returned to the police academy dormitory where he was twenty years old - a time when the upper bunk brother was still alive, the woman who would become his wife in the future did not know him, and the murderer who killed him was still dormant in the dark.
With twenty years of criminal investigation experience, countless memories of life and death, and a belly full of secrets that "shouldn't be known", Zhou Yunsheng started this life.
He has to hide his edge under the training of the "Ghost Sees Sorrow" instructor, he has to play nice in front of his ignorant roommates, he has to stay calm in front of Han Bing, who is as proud as a little rooster - and he has to get rid of those bastards who got away with justice in his previous life one by one before the tragedy happens.
But can doing it again really change everything?
When he discovered that the man who was a gangster in his previous life appeared in front of him in advance in this life; when the drug lord he traced revealed a network of relationships that spanned the black and white; when his most trusted leader may be the mole who had been lurking for twenty years - Zhou Yunsheng understood that what fate had given him was not a chance to "do it over again", but a ticket to "unveil the truth".
This is not a person's rebirth and counterattack, but a group of little people struggling to survive in the torrent of fate.
He Yong, who is talkative but loyal, Meng Hu, who is taciturn but his background is a mystery, Han Bing, who is proud and strong but can secretly blush, Shen Mo, who is sinister and cold but was once an undercover policeman - some of these people died in their previous lives, some were injured in their previous lives, and some became enemies in their previous lives.
In this life, they will live together.
