Jiang Feng advances 6,600 for a business trip, but gets only 600 approved for reimbursement. Supervisor Wang Dahai and finance officer Li Juan dock employee expense reports, privately opening secret accounts to withhold funds under the guise of uniform salary card processing. Enduring this, Jiang Feng gathers evidence, teams up with fellow victims Lao Liu and Xiao Zhang to organize receipts and transaction records, and anonymously reports them to group audit. Just as the group's tens-of-millions project urgently needs an overseas deployment where everyone is wary of reimbursement traps and no one is willing to go, Jiang Feng publicly exposes the inside story, bringing about a thorough audit inspection. Wang Dahai and Li Juan's embezzlement of duties is exposed, and all funds are refunded in full. Jiang Feng's team wins the tens-of-millions project, and he is promoted to branch general manager, implementing new reimbursement regulations to root out the chaos of out-of-pocket advances and withheld funds.
