The first in a series of 3 movies about a female yakuza
It's been a year since the father of Yukiko Eguchi, an ivory craftsman, was murdered and the investigation led by Inspector Kinoshita is at a standstill. What Yukiko did not reveal to the police is that her father also made rigged dice for the yakuza. She practices rolling the dice so she can scour the gambling dens and find out who her father's killer is. Shōji Itō, a professional gambler fresh out of Abashiri prison, helps her in her quest and becomes her lover.
