After being undercover for ten years, I came back and became a suspect! My superior who personally sent me to lurk in the criminal group completely denied my code name of "Nightingale", canceled my police number, and falsified my death record. It turns out that there is an internal corruption conspiracy hidden behind it, and mysterious helpers appear one after another in desperate situations. In this life-and-death battle to clear my name, I can only win, not lose!
