A vampire named Saya, who is part of a covert government agency that hunts and destroys demons in a post-WWII Japan, is inserted in a military school to discover which one of her classmates is a demon is disguise.
I always thought the animated Blood: The Last Vampire, which this movie is based upon, had the potential to be something great, but was a bit disappointing. It seemed like it was an extended episode of an animated tv show, rather than a stand alone film.
This time around, Blood is directed by Chris Nahon. The movie has a May 29,2009 release date for Japan and a tentative release date in March for the USA. My guess, however, is this will come and go and could possibly find an audience on DVD.
