Although Han-soo's injustice gets resolved through Moon Sang-ho's involvement, this time, a photo of Dae-woong and Seo-jin together gives rise to the unfair hiring issue that has been dying down. Se-woong takes this opportunity to take down Dae-woong and orders Cha-il to audit the case. When Cha-il reports without results, Se-woong rejects it and hires an external audit team to take over.

The audit team successfully tracks down the employee who joined the company through improper means, only to be shocked when an unexpected culprit is revealed. Meanwhile, Cha-il's aggressive auditing methods draw unwanted attention and place him under scrutiny. As the audit on Cha-il progresses, the team uncovers new information about his past.

Following the death of former president Gun-woong, JU Construction is entering a transitional phase where new leadership will soon be established. In the midst of this uncertainty, Cha-il uncovers a massive corruption scandal within the company. As he investigates further, he discovers that the corruption is deeply entrenched within the core of the organization. Cha-il vows to wage a battle against the primary culprit exploiting the company.
