Bad Blood.

When the evil powers of darkness enlightens one vampire, Eric Henswich, the mortal world will go to Hell. Turning worthy mortals into ghoulish monstrosities, and gruesomely disposing the rest of the human race; leaving rotting carnage to clutter the Earth's face... you can't stop the unstoppable, not even slow them down. This new breed of vampires no longer need fresh blood to keep them alive. They'll live forever of the pure essence of the evil that fills their inhumane hearts.
