A well-planned massacre turned the carefree Xie Hongyu into a wanted criminal. He was forced to hide in Tibet and lived in fear all day long. As for the twin brother Xie Hongfeng, who is the captain of the criminal investigation detachment, his heart is full of contradictions and pain: he firmly believes in his brother's innocence, but he has to face the pressure of the police force and the principle of avoidance of relatives.
After resigning in anger, Xie Hongfeng secretly joined forces with his younger brother Xie Hongyu. They appeared in the police force as a "non-staff consultant" one day and one night, playing two roles during the day and night, to track down the truth.
During the day, the gentle and thoughtful Xie Hongfeng appears in the police force and uses his professional knowledge and experience to help solve the case; at night, the cynical and agile Xie Hongyu sneaks into the police station and secretly investigates the files on the murder case.

As the investigation deepened, they discovered that there was a huge conspiracy hidden behind the murder case, involving corruption within the police force and collusion with evil forces. The two brothers worked step by step and launched a thrilling contest with the mastermind behind the scenes.
In the end, they revealed the truth and brought the murderer to justice. Xie Hongyu was cleared of his grievances and the two brothers reconciled. However, they also paid a huge price. The carefreeness and aboveboardness they once had no longer exist...
