Shen Yubai was kicked out by his former employer for reporting data fraud and was parachuted into the QC Department of Hengrui Pharmaceutical. On the first day of joining the company, female boss Wen Zhihui came over with a report that exceeded the standard - someone wanted to release someone in violation of regulations, but he insisted on using his professionalism to fight to the end. Impurities exceeding standards, data tampering, FDA raids, and the masterminds behind the scenes are closing in step by step. The two went from tit-for-tat to fighting side by side, fighting their way through the undercurrent of the pharmaceutical company. When love and principles clashed, he said: "The data I insist on never lie to others. Including loving you." This is a counterattack by a quality inspector and a two-way rush by two idealists.
