Following the death of two of his closest allies, Bruce Wayne has gone into self-isolation, only operating as Batman in Gotham during the night. Over the years, Batman has caught the attention of Professor Hugo Strange, a psychiatrist at Arkham Asylum. Attempting to study the mind of the Bat, Hugo works with the inmates of Arkham to take over the asylum, drawing in Batman right where they want him. Bruce is forced to fight his own past demons, and begins to question if he really is as much of a monster as the villains locked away in Arkham.
