Seong-ryong begins his new job at TQ Group but receives a chilly reception from his department. Prosecutor Seo Yool also takes a new position and plans to use Seong-ryong for his own ends.

Seong-ryong has earned a new upstanding reputation by his accidental action, but his department still isn’t convinced. Ha-gyeong suspects the driver of being involved in something bigger but is unable to find evidence.

After being arrested, Seong-ryong realizes he is in over his head with TQ Group. Ha-gyeong learns more about the company’s corruption from Choo Nam-ho.

Seong-ryong is unexpectedly brought in to deal with the company’s Chinese partners. A strike at TQ Delivery also presents a problem.

The handling of the union strike causes Chairman Park Hyeon-do to order Seong-ryong to be fired. Yool finds out that Ha-gyeong and Madam Jang Yoo-seon are working together.

After Seong-ryong’s latest arrest, TQ Group tries to force him to quit. Nam-ho convinces him to rent a room in his house.

Seong-ryong is as disruptive as possible while threatening to expose the company to the press. Won Gi-ok worries about his father when the labor union protestors are arrested.

Business Operations begins work on a revival plan that has higher stakes than they expected. The higher-ups involved in illegal activity scramble to get rid of evidence.

Work continues on the revival plan down to the wire. Seong-ryong tracks down people to testify against TQ Delivery.

Seong-ryong is overcome with guilt after the failure of his plan, but his coworkers, now in new departments, stay positive while striking back at those who wronged them.
