Can corporate politics turn a bad person into a good person? Kim Seong-ryong is a skilled accountant who works for gangsters. He makes his way into a company called TQ Group as a middle manager in the accounting department with the intention of embezzling money from the company. As he contends with hot-shot accountant Yoon Ha-gyeong, financial prodigy Seo Yool and peppy intern Hong Ga-eun, Seong-ryong finds himself embroiled in office politics and notices other shenanigans by those in power that threaten to bring down the company. Seong-ryong slowly comes to realize that he’d rather fight against corporate corruption and fight for employees’ rights than complete the mission he originally came to do. Can he succeed at his new objective against all odds?
