A vampire named Saya, who is part of 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 in disguise.
I just wanted to see this movie because of Jeon Ji Hyeon. Her performance did not disappointment me even for a second. I believe this is her best performance in a action movie.
The movie was not bad despite it's poor rating. The stunt choreography,cinematography, screenplay, music, Jeon Ji Hyun's performance lifts the movie, whereas average graphics, normal plot, too much blood shed scenes are negatives to the movie. An action movie with really very good stunts.
The movie doesn't deserve a rating of 6.7. It is one time watchable.
