Administrative staff Lin Wan, who was treated like a free nanny by her colleagues, suddenly refuses to help anymore! When everyone teams up to make things difficult for her, she publicly reveals her identity as a special inspection commissioner and exposes a reimbursement fraud scheme. Little did she know, behind the petty corruption hid senior corporate executives, triggering wave after wave of frame-ups, fund cutoffs, and forced signings. She and Zhang Lei join forces to investigate, uncovering a dark web of interests through one counterattack after another, while teaching those forced to take the fall how to say no: this favor, I am not helping anymore!
