The human population of planet Earth has been decimated by bloodthirsty vampires, and now the only hope for the few remaining survivors lies in the skills of one man who always lived by the sword. Tao (Steven Seagal) is a katana master who never met a vampire he didn't want to slay. When roving packs of vampires force the few uninfected survivors to seek refuge in an abandoned hospital, the only hope for the human race lies with Tao's special squad of ex-military vigilantes. The only cure for these creatures is execution, and that's Tao's specialty. As the hunt gets underway, Tao and his team make it their mission to ensure that the creatures of the night don't inherit the Earth.
