On the day of a colleague's wedding, project manager Meng Ning is asked to sign off on a final payment of 216,000 yuan, and the source of the deduction turns out to be the deposit for the client's wedding project. She refuses to misappropriate client funds, but as a result offends the leadership, gets her performance docked, and sees her projects sidelined. Faced with false reimbursements, irregular procurement, erroneous delivery, and mounting pressure, Meng Ning always sticks to her principles, uses evidence to track down every single expense, and safeguards the client's rights and interests. In the end, she not only uncovers the profit chain behind the scenes, but also prompts the company to re-establish standard procedures.
