One day five years ago, criminal investigation captain Lan Feng led criminal psychology expert Jiang Miao (formerly known as Qiu Xue) and instructor Qing Xuan to the river, waiting for the arrival of the false organization "Fei". The person codenamed "Fei" was "Qingxuan" who had been lurking in the police for two years. After she stunned Lan Feng, she pushed Jiang Miao into the river, and then disappeared without a trace with Jiang Miao.
Five years later, Jiang Miao, who had been missing for many years, was found by the Mu Bureau and learned self-defense skills. The Mu Bureau conducted a series of physical tests on her, which Jiang Miao passed. She was then assigned to serve as the deputy criminal investigation team under Lan Feng.
Under the leadership of the two men, the criminal investigation team cracked many major cases, and finally took down all the false organizations through clues during the investigation.
Purpose: They are first the people's policemen who maintain the tranquility of the country, and then they are lovers who love each other.
