Against the Dark

Katana master Tao leads a special ops squad of ex-military vigilantes on a massacre mission, their target: vampires on an post apocalyptic globe. Tao is the survivors' only hope and he knows the only cure is execution.
When most of the population of Earth is infected by a virus and transformed into flesh eaters and blood drinking creatures, a group of hunters lead by Tao and his sword chase the vampire zombies to eliminate them. Six non-infected survivors try to find the exit of an abandoned hospital crowded of the infected creatures. Meanwhile, the military is ready to bomb the whole area.
