Sinopsis

A deep mist envelops the port city of Yokohama. The scent of crime is everywhere. As an executive member of a drug trafficking syndicate, Kano is pretty high up in the food chain, but "status" bears no value to him. All he cares for is Ayako, the boss' mistress. After one last job, they intend to run off together to Hong Kong, but their plans are hindered when an uninvited yakuza stirs up a vicious shootout. In the midst of it all, Ayako is kidnapped.
