Ryunosuke awakens in the forest having no more idea what happened that previous night, as he'd been drunk & hallucinatory. He is surrounded by corpses & can surmise it's his own handiwork.
A wandering yakuza in search for the man responsible for slicing up his father and an amateur samurai searching for the whereabouts of his own father are thrown together on the outskirts of a mob infested seaside village.
