Yu Chu, the soon-to-be head of the Marketing Department, is maliciously framed by an intern named Zhao Ling. Zhao falsifies expense amounts and edits audio recordings to accuse Yu Chu of exploiting her subordinates. Deputy Director Wang Chonglin and Department Head Chen Ming, who are involved in corruption and favor Zhao Ling, intend to pin the financial misconduct on Yu Chu. Calmly gathering complete evidence, Yu Chu joins forces with her righteous colleagues to dig deeper and uncover solid proof of everyone's fraud, corruption, and collusion. At the review meeting, she presents all the evidence in public, prompting the disciplinary inspection team to launch a thorough investigation and hold those responsible accountable according to regulations.
