Xiang Rong (Michael Miu), who was born in "red trousers", was promoted from an ordinary policeman to a senior inspector of the Drug Enforcement Bureau's action group, surrounded by a group of colleagues who are closer than brothers. Rong, who has been committed to cracking down on drug traffickers, met something that changed his life a year ago. On that day, Rong led the team to sweep drugs, and drug dealers scattered. Rong and others immediately catch up. At the same time, a brother named Zheng Zhicheng (Luo Lelin) finds a sum of money on the ground and keeps it for himself. Zhicheng is desperate because his wife's condition is getting worse and he needs a large sum of money urgently. Only after the incident did Rong know that a group of brothers begged Rong not to report Zhicheng. He couldn't stand everyone's entreaties and the feelings between his brothers, so he promised not to report that his brother had embezzled the money.
Just when everyone thought everything was going well, Rong received a phone call a few months later, and even received an image on the phone, saying that Zhicheng had been photographed embezzling money, so he should be honored to work for him, or all the evidence would be made public. If you don't promise to work for him, Rong and his brothers will be ruined, and all the brothers will suffer jail because of their wrong decisions. If he agrees to work for him, Rong will bear the name of "black policeman" for life and be controlled by mysterious agents forever.
Drugs are not poisonous, but people are the most poisonous.
Pan Xueli (Huang Zhixian), the chief inspector of the Narcotics Bureau's Action Team, looks generous, but in fact he is narrow-minded and selfish. He just wants to be the police chief by hook or by crook, and he is very jealous of Xerox, hoping to extract evidence of Xerox's mistakes from time to time. I know that my subordinate Rong may be a "black policeman", but there is no evidence. However, the shrewd man deeply hopes to kill Rong, take credit in front of the boss, go up a storey still higher and make a career in the company, and even alienate Rong and his brothers, hoping to catch everyone.
When she learned that Gao Xixuan (Guan Enna), a subordinate of Xerox, was originally the only daughter of the Assistant Commissioner of Police, Betty abandoned her girlfriend who had been in contact for many years and began to pursue cierre, hoping that their relationship would skyrocket, so she tried every means to destroy the relationship with Xerox. Later, Li Xue discovers that Shile Wei (Raymond Lin) has an unusual relationship with the informant Chen Jiabi (Xu Zishan), so she plays tricks to separate Gaby from Xerox, making Gaby her pawn against Xerox.
Emotional choice is more expensive than sincerity.
Yu Yongtong () married Rong because he thought he was an enterprising policeman, but Rong was promoted to senior inspector, but his career was stagnant. It is difficult for Yongtong to understand the attitude of not being able to make progress, and think that people should climb high and look far. Gradually, the differences between the two grew bigger and bigger, and finally they separated because of their disagreement. However, a few years later, Yongtong returned to Hong Kong with several senior academic titles and served as the chief inspector of the Wealth Investigation Division of the Narcotics Bureau. Because of the need of work, Rong and he have to cooperate with each other. After many times of cooperation, the two began to regain their feelings, unconsciously changing their daily life style and accommodating each other, making Yongtong realize his shallowness of love.
Xerox borrowed Gaby's home to spy on drug dealers because of an operation, and the two met. Later, he found that Gaby had the potential to become an informant, and she was lured to help herself in an operation. Gaby lived up to expectations, helped him solve the case successfully, and even let her taste the indirect revenge of arresting drug dealers. Since then, the two have established the relationship between the police and the informant. In constant contact, Gaby and Xerox gradually fell in love, and even developed beyond the relationship between ordinary police and informants. However, at this time, Gaby felt that he was from a humble background and was not worthy of Xerox. He began to escape from Xerox's love for himself and suffered the pain of thinking about love but not daring to love. On the contrary, Xerox doesn't care about Gaby's birth. She loves her even more.
