Taketo is the only son of the President of Nogawa Industries, a well known and powerful corporation, which is said to be in a connection with the yakuza. One day, Taketo going on his usual way to the company's building for begging money from his father, witnesses how this father's car has a traffic accident with a young woman named Kitazawa Yukie. Being in a hurry on his way to an airport, his father uses the occasion to put his good for nothing son to the test by letting him handle the litigation. If he wants money, he will have to settle the case amicably by making the woman his by any means necessary. If he can do that, he will also introduce him to his shady business that he had refused until now by lack of trust. Now Taketo has only four days before his father's returning to meet his expectations.
