At a large technology company with a rigid hierarchy, middle manager Li Ming is left unable to file his expense claims after his direct supervisor dies unexpectedly. In desperation, he makes a wild decision: he sneaks into a funeral home late at night, takes his late supervisor’s hand from the ice coffin, and presses its red fingerprint onto an invoice. This shocking act not only sends the company into an uproar, but also exposes a major financial fraud involving the company’s senior executives.
During the investigation, Li Ming teams up with finance supervisor Wang Li to gradually uncover the truth. In the end, they bring the mastermind to justice, and Li Ming finally gets his expenses reimbursed.
