In Japan, during the reign of Shogun Yoshimune, it is the
era of the samurai and the ninja. Many villages are outwardly
peaceful, but a twisted sexual underbelly exists that affects
more than just the criminals. Kaede and her sister become
victims of this when the elder girl is raped and commits
suicide shortly thereafter. Kaede seeks vengeance, and a
lady ninja nun who hears of the events aids her in the search.
There is more to the story behind the rape, however, and the
lies and secrets are slowly revealed behind a trail of clothing,
sweat, and blood.
