Synopsis for "Book One"
Part One: The Cave
The story begins with Alfred recounting his adventures with Batman and sharing his experience working with the vigilante. Batman had noticed that someone had been drawing lines of chalk across Gotham, later realizing that it had been what was apparently him dead, later bringing him to Crime Alley, where his parents were murdered. When he had arrived in Crime Alley, he saw a young boy on his knees with an umbrella. When he saw the boy, he saw that his body had been decomposed. Suddenly, he activated a mechanism trap built into the boy, getting shot by a revolver in the boy's hand.
Next thing Bruce knew, he was in Arkham Asylum, next to a doctor named Redmund Hudd, who claimed that they had both been there for almost twenty years. Upon this revelation, Bruce panicked and demanded to be released, until Alfred had appeared in the room and was delighted to see him. Alfred claimed that Bruce had killed his parents in Crime Alley, causing the latter to break down, not believing that it was real, implying that it was a trick by Mad Hatter or Scarecrow. Then, Alfred left, while Bruce was sent to solitary confinement.
Later, Alfred returned to visit Bruce again and brought him back his cowl, which was now combined with an Arkham inmate uniform. Suddenly, Bruce asked for Alfred to give him the suit.
Part Two: The Right Hand
Bruce had put on the suit and began to attack the guards in an attempt to escape from Arkham. Eventually, Alfred caught up with Bruce and pleaded with him to stop, claiming that there was nothing left for him and that Gotham, his friends, and everything he knew was gone.
Later, Bruce had woken up buried in sand until he came upon the Joker, whose head was now in a hanging jar. The Joker claimed that he did not remember much about what happened to him. As Speed Force storms began, Bruce took the Joker's head with him and trekked around the desert.
Part Three: The Asylum
Bruce and the Joker had arrived and found the destroyed Green Lantern Power Battery with Mogo, who had been leached to death by Brainiac, in orbit. Suddenly, the two were attacked by giant baby energy constructs operated by users with lack of willpower. Batman attempted to fight the giant babies until he was saved by Vixen, who took him inside of an armored vehicle, which was being driven by Poison Ivy.
Part Four: Echolocation
Vixen and Ivy had taken Batman to Gemworld, where he was being kept prisoner. Suddenly, Wonder Woman had appeared, wearing the Helmet of Fate. Diana claimed that Bruce had killed the world and that there were only 100,000 people left in Gemworld. Then, she told Bruce that Lex Luthor had indirectly caused everything, manipulating the public into becoming lawless, resulting in the deaths of Aquaman, Green Arrow, and Black Canary. Then, they went to war against Darkseid, but lost. She also claimed that Superman was dead. Diana said that she was considering relocating their people to the realm of Hades. Afterwards, Bruce had encountered a young boy who asked if he was really Batman. The boy asked him to teach him how to see in the dark, which Bruce responded by telling him about echolocation and yelling out loud with the boy, which the Joker had heard from nearby.
Later on, Diana went back to look for Bruce and tell him about her plans, but found that he had disappeared with his Batsuit.
