Imagine a world in which no one dies ? not from accidents, murders, or natural disasters. It sounds idyllic, but just because no one can die doesn't mean they shouldn't die. Ra's al Ghul has left a world filled with miserable, self-aware, reanimated corpses for the Batman to deal with. And when Gotham City's hospitals, homes and streets begin filling with the undead, the Dark Knight is the only one with a chance to discover the secret behind their continued animation. In order to do so, he must discover Ra?s al Ghul?s centuries of secret world travels! Set of both issues.
