In this world, everyone's destiny, talent, and luck are condensed into an invisible line of "fate". And a small number of people with special abilities called "fate masters" can see and manipulate these threads. Some people steal other people's lives and become rich overnight; some people have everything taken away and become dust. A secret underground world revolving around destiny quietly operates in the bustling city.
Jiang Chen, as the guardian of tradition, is committed to maintaining the natural flow of fate and hunting down predators in the shadows of the city. Su Wanying, a top "fate hunter" who walks in the gray area, only moves for profit, and completes every "fate correction" task accurately and efficiently.
When a huge "fate storm" swept across the entire Donghai City, the fate of countless people was maliciously distorted, and two people with completely opposite positions were forced to join forces. One wants to protect order, and the other wants to seize opportunities. In repeated confrontations and cooperation, they not only have to fight against the mastermind who attempts to subvert the balance of the destiny of the entire world, but also face the feelings quietly growing in each other's hearts that cannot be defined by "fate".
