The Bohachi Clan, the most vile, corrupt organization with ties deep in the Shogunate, have controlled the flesh trade in Japan for generations. When threatened by a competitor, they employ Saburai, a nihilistic ronin on the verge of self destruction. Blood gushes and limbs fly for anyone who stands against Saburai as he instills the Way of the Bohachi.

In feudal Japan, a group of samurai warriors, yakuza gangsters, and erotic women cross paths, leading to bloody confrontations and hidden secrets. Based on a popular comic series, this action-packed drama explores the themes of bushido and honor.
