At Tokyo Daiichi Bank, an unprecedented crisis is quietly approaching.The salary allocation work of the major customer Itami Group was originally a daily and important service of the bank.

On payday, a shocking thing happened - the salary data of about 10,000 people disappeared, causing the salaries to be unable to be recorded normally.The news quickly spread within the bank, causing an uproar.

In order to find out the truth as soon as possible and properly deal with this scandal, the bank's senior officials decided to set up a special investigation committee.As the backbone of the business, Xiao Wu (played by Xing) and Soma (played by Kamikawa Takaya) were also selected as one of the investigation committee members.

This task is not only related to the reputation of the bank, but also involves the livelihood and interests of many employees. Therefore, the responsibility is heavy and cannot be missed.

Xiao Wu and Xiang Ma quickly plunged into intense investigation work.

They first sorted out the salary payment process of Itami Group and found some suspicious clues.Then, they began to investigate the personnel and links that may be involved one by one, looking for any clues that the salary data was missing.

During the investigation, they encountered many difficulties and challenges.Some employees choose to remain silent for fear of being implicated, and some clues are difficult to trace because they are so old.
