The Director explains the film here.
Follows a scorned geisha who creates a magical cup made of tears that causes any man who drinks from it to fall into a permanent sleep. One night the cup is stolen, setting off a chain of events that threatens civil war amongst the clans. Taro, a gifted samurai, sets out to find the cup and one who can break the spell.
Beautiful and badass looking Samurai film, in the same style of Sin City/300. I have to see this film on the big screen.
