Hanzawa Naoki works for Tokyo Chuo Bank as the head of the Loans Division at their Osaka Nishi branch. The overbearing branch manager, Asano, forces him to award an unsecured loan of 500 million yen to Nishi Osaka Steel. On the surface, Nishi Osaka Steel seems like a very reputable company, but in actual fact it is a company in deep trouble. Debt-ridden, the company accountants resort to window-dressing the financial statements in order to hide the truth from the public. Three months after the loan, Nishi Osaka Steel goes bankrupt and the ambitious and power-hungry Asano makes Hanzawa the scapegoat for the 500 million loss. Hanzawa is called to Tokyo to answer to the internal investigations team, where he vehemently denies responsibility for the loss, and swears to recover the 500 million yen. That is the only course of action for Hanzawa, if he wants to survive in the banking industry.
