After her father, a detective, died in the line of duty many years ago, Tian Yan, who inherited her father's blood, also became a police officer, but she worked as a traffic police officer. On her first day at work, she offended the lawyer Duanmu Changchun who was rushing to appear in court for following the rules, but the latter did not argue with her at that time, which made her feel proud. After the leader of the team, Li, learned about the whole situation, he criticized her for not doing things properly because Duanmu Changchun was very difficult to deal with. Sure enough, before the anger she sparked when she was scolded subsided, the team received a subpoena from the court. Under the intimidation of Team Li and the instructor, Tian Yan, in order to avoid implicating her personal grievances with Duanmu Changchun in the team, bravely sought reconciliation with Duanmu Changchun. Unexpectedly, the two strangers became lovers because of this. However, their love journey was full of twists and turns due to the deliberate scheming of Ye Qing, who had a crush on Duanmu Changchun.
