Japanese superstar Kade Matsumisha stars as a deadly female ninja who single-handedly goes up against an entire temple of evil on a mission to assassinate the rebel lord who plots to betray the Taiko, and finds herself forced to draw on every weapon at her disposal to seek vengeance on the nefarious ruler who nearly took her life. In the time of warring states, Lord Daizen Osakabe betrays the Taiko clan by aligning himself with the Tokagawa. Now, it's up to the female ninja Murasame (Matsumisha) to bring the traitorous Lord Osakabe to justice. Realizing that the chances of her returning home from the mission are slim to none, Murasame unleashes a ferocity the likes of which her target has never seen. Just as she is about to emerge victorious, however, the daimyo's samurai strikes her down. Later Murasame awakens deep in the bowels of a mysterious convent. But is this secluded abbess actually the safe-haven it appears to be, or is Murasame about to discover that the worst is yet to come? Slowly drawn into a treacherous web of slavery and deception, the vengeful female ninja vows to escape the heavily fortified compound, and ensure that the person responsible for her internment there suffers the ultimate consequences.
