A werewolf stalks the streets of Gotham City, bringing violence and carnage in its wake and drawing the attention of the city’s greatest defender: Batman. But when the Dark Knight becomes the newest victim of the Lycan’s curse, it tests the hero as never before. Zatanna and John Constantine offer all the help their ancient magics can provide, but in the end, Batman must make an impossible decision to lift the curse: sacrifice his own life…or take another’s!
