男の挑戦

Hiroshi (Ishizaka), the second son of Nippon Automobile president Tsuda (Ozawa), comes to the company's speed test track every day and drives his car at breakneck speed. One day, no one tried to criticise him, but only test driver Inoki (Kurizuka) accused him of being selfish. Angered, Hiroshi challenged Inoki to a race, but lost miserably. From then on, Hiroshi began to seriously hone his skills as a racer in order to overtake Inoki.
