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.

Naoki Hanzawa (Masato Sakai) works as a loan manager at the Osaka Nishi branch of Tokyo Central Bank. One day, Naoki makes a loan contract for 500 million yen with Nishi Osaka Steel Company. Naoki didn't want to approve the loan, but he had to due to the branch manager's order. Nishi Osaka Steel Company seems financially stable, but the company actually hides massive amounts of debt through fraudulent accounts. The company is caught. Three months later, Nishi Osaka Steel Company goes bankrupt.

The bank's branch manager is Asano. He is an ambitious man and tries to shift the blame to Naoki. Naoki then attends an inquiry about the loan failure at the bank's headquarters in Tokyo. Naoki denies fault and promises to retrieve the 500 million yen loan. He did this because it's the only way for Naoki to survive as a banker.
