Maseru checks out a small boxing gym and begins to train as a boxer. Shinji,
inevitably, follows suit. . . . and turns out to have more strength, talent
and persistence than his friend. Masaru soon quits the sport, but Shinji
trains hard and begins to win some junior bouts. The next time Shinji sees
him, Masaru has joined the Yakuza as an ambitious young hoodlum . . . Two
or three years later, Masaru and Shinji run into each other again by chance.
They make their way back to their old school . . .
