Tzuzuki is a Ronin, a masterless samurai living at the very end of the long period of peace through to the mid 19th Century which made such swordsmen surplus to Japanese society. He seems happy wandering, helping farmers in exchange for food, but trouble is stirring in Edo and he realises he must go there - it is unclear whether out of duty or hope for his own future. He seems to get lucky when a wandering master swordsman asks him to join him on a mission to help the Shogun against his enemies. This seems to set us up for a traditional clash between desire and duty, modernity and tradition, but the film takes a surprising turn when a few tough guy wanderers arrive in the village and Tzuzuki is hit with a fever, meaning he has to stay longer.
The film takes a strange turn when we realise that Tzuzuki is not just reluctant to leave his farmer friends, but is almost pathologically unable to translate his sword skills into the real job of killing men - even deserving men. The fever itself seems to encompass his whole world. Suddenly everything is not what it seems - not the master swordsman, not the sweet village girl who seems to love Tzuzuki, not the tough but seemingly good hearted wanderers.
This is a very modern take on the traditional Samurai genre. Plenty of previous Samurai movies examine the twisted ethos of the warrior class, but few examine so much how killing itself destroys the humanity of the swordsman. It is strikingly filmed and directed - normally I hate shaky-cam films, but its used effectively here to create a hallucinogenic atmosphere of confusion and chaos. The settings are very beautiful and effectively caught by the cinematography and the short running time of the film means that there is no flab at all - its a gripping, tight film, with its only flaw really that we never really get to understand the characters real motivations. Nevertheless, this is definitely one of the best modern samurai films I've seen in some time.
