On October 31, 2014, a year and a few months before the events of Batman v Superman, Bruce Wayne is trying to recover from Jason Todd's death after breaking the Joker's teeth and sending him to Arkham. But when the Joker mounts a riot at the asylum, a violent Batman must deal with the consequences of the actions of his greatest rival and others of his greatest enemies as he infiltrates the depths of Arkham Asylum. Will Bruce succumb to rage or will he stick to his main rule? Only time will tell, but after this night, Gotham will never be the same!
