After being released from prison Kunihiro (Harada) finds himself in a changed world, the code of the Yakuza has been replaced with the facade of legitimate businessmen who live only for money, not honour. Reluctantly, Kunihiro is drawn back to the world he left behind and after falling for a piano player at a nightclub finds himself embarking upon an act of revenge that threatens to cost him not only his freedom but also the lives of those around him.
