Lady Ninja Kaede (2007)

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 the wealthy and impoverished alike. When one of the village elders commits suicide after being sexually attacked, Kaede and her sister decide to take justice into their own hands and track down the perpetrator. Aided by a lethal lady ninja nun who believes in Old Testament-style retribution, the two sisters embark on their bloody mission of vengeance. Along the way, the three women slice and dice their way through lies and secrets while discovering that the story behind the sexual attack is much more complex than any of them suspected. They leave behind a trail of clothing, sweat, and blood.
