The city is in chaos! Batman has escaped a nightmare, but the evil lord Bane – the man who once took down the Dark Knight – is still secretly running Arkham Asylum. As Batman battles his demons and seeks to regain control, questions arise about his true nature: can Batman truly overcome the horrors of his past? When Bruce Wayne disappears, another Dark Knight rises, but not the one Gotham knows: Batman from Flashpoint's world has arrived in this reality and acts as Bane's right-hand man. With the support of Catwoman and the Bat-Family, can Bruce muster the strength to face Bane and his mirror-universe father once and for all?
