The story takes place in contemporary times, a typical industrial city. There are both old machinery factories and emerging government affairs centers here, forming a social scene where traditional manufacturing and modern bureaucracy are intertwined. The civil service examination is an important channel for young people in this city to change their destiny, and the disciplinary inspection and supervision system, as the core department of power supervision, is both mysterious and full of tension. There are undercurrents surging in the officialdom, the network of relationships is intricate, and every decision affects the interests of multiple parties. In this context, when an ordinary person steps into the system, he will face the collision of ideals and reality, the choice of principle and compromise. Every step he takes may trigger a chain reaction and change the fate of himself and others.
