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.

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.
