Lin Qiang (Bai Yu) was originally the deputy general manager of the credit approval department of Lianzhong Bank's head office. Because he was unwilling to sign a problematic loan, he offended his superiors and was demoted to the Longyuan branch, which had the lowest performance. His close friend Zheng Shuai (Wang Youjun), who entered the bank at the same time as him, was also implicated and demoted. The Longyuan branch was in chaos, and Lin Qiang quickly discovered the crux of the Longyuan branch with his professional ability and helped the tellers of the Longyuan branch to fight for their deserved interests. This angered the president Hao Wei, who put pressure on Lin Qiang everywhere. Lin Qiang, whose career was in crisis, had to fight back and traced the source to find the problem of the loan case. In the end, the problem was cleared up and Lin Qiang realized his career ideal.
