The internal audit department is embroiled in a complex internal conflict, with a young member having a tense relationship with his team leader over his involvement in a suspected bullying incident.However, there is more than meets the eye, and this incident not only tests the protagonists, but also makes the case they pursue extremely difficult.As the audit work progressed, the auditors gradually came into contact with deep internal information closely related to the latest incident, thereby revealing a major criminal plan that may involve billions of won.Urgency forces them to act quickly to prevent potential losses.

The bullying escalates quickly, and when Han Soo keenly catches signs of a data breach, the unease within the team suddenly intensifies.Faced with Shen Ciying's demand for conclusive evidence, the dispute between Han Zhu and Shen Ciying intensified, and finally Han Zhu angrily decided to act alone.He adopted a risky strategy of breaking into the company's systems without permission, only to make the situation more chaotic.

As the investigation deepened, a shocking fact gradually became clear: someone within the Technology Development Department attempted to illegally sell J-BIMS links, but the relevant evidence mysteriously evaporated.While Shin Ci Young apologized to the team leader Li Zhixun, he privately expressed strong dissatisfaction with Han Soo's behavior and expressed doubts about the team leader's true identity.He secretly allowed Han Soo to continue the investigation, but unfortunately, Han Soo's reckless behavior was blocked again and he fell into danger.

At the critical moment, Shen Ciying stepped forward, rescued Han Su and successfully captured the suspect.However, the suspect was just a passport forger. Although Li Zhixun's suspicion was increased, he was not directly proven to have committed the crime of stealing J-BIMS.Faced with this dilemma, audit teams have to adjust their tactics to deal with more complex situations.

At the same time, Minister Park of the Technology Development Department stayed up all night because he was assigned extra work by Li Zhixun, but was accidentally intercepted by the audit team in the early morning.Shin Ciying brought Minister Park to the office for a detailed discussion on the grounds of investigating Yin Yu's bullying case.Facing the pressure from the audit team, Minister Park felt helpless, but he also realized the seriousness of this case.

While Han Soo was focusing on hacking technology, Shin Ci Young was investigating Li Zhixun's background in depth and discovered his bad behavior of workplace bullying, and suspected that Minister Park was also one of the victims.However, they did not openly discuss these sensitive topics.Seo Jin promptly provided key clues, revealing that in addition to Han Soo, there were other auditors who had secret contacts with the team leader, and showed a list of evidence that Minister Park violated safety regulations.This evidence% is actually a trap set by Li Zhixun, aiming to transfer the accusation to Minister Park.
