Prologue Nine months after the Joker's death, Gotham City has seen a significant drop in crime, yet Batman remains on high alert, sensing an emerging danger. Before his demise, the Joker had sent his altered blood to Gotham's hospitals, infecting several patients. Although most were successfully treated, those left untreated are beginning to transform both physically and behaviorally into the Joker. Batman works to find a solution to the mutations, assigning Robin to monitor the infected individuals. The Arkham Knight On Halloween, Scarecrow releases a new form of Fear Gas in a restaurant, warning of a citywide release. Six million residents are evacuated, but the criminal underworld remains, leaving Commissioner James Gordon and the Gotham City Police outnumbered. Batman tracks Scarecrow to a rooftop hideout, where he unexpectedly rescues Poison Ivy from Scarecrow's henchmen. In a temporary Batcave within Gotham's Clock Tower, Barbara Gordon gathers intelligence on Scarecrow's toxin, tracing its creation to Ace Chemicals. Batman investigates but is met by the enigmatic "Arkham Knight" and his forces, who command a large army of unmanned tanks. Battling through the enemy, Batman learns from workers that Scarecrow plans a massive chemical explosion that would blanket the entire eastern seaboard in fear toxin. He confronts Scarecrow, who reveals that Barbara has been taken by the Arkham Knight before fleeing. As Batman reduces the blast radius, he is exposed to the toxin, which interacts with his own altered blood, causing visions of the Joker. After escaping the collapsing Ace Chemicals, Batman reveals to Gordon that Barbara is involved in his mission, prompting Gordon to vow to find her without Batman's aid. Scarecrow's Plans Batman follows the Arkham Knight into a subterranean tunnel system, seeking information about Barbara, but is instead ambushed. He pursues the fleeing convoy and discovers the driver is a fake, using a voice modulator to mimic the Arkham Knight. Interrogating the driver, Batman learns the group is heading to the North Refrigeration. With Nightwing, he questions the Penguin, who reveals that the Knight and Scarecrow are meeting with a corporate executive named Simon Stagg, owner of a pharmaceutical firm. Upon boarding Stagg's airship, Batman uncovers that Scarecrow hired Stagg to build a device called the "Cloudburst," but Stagg attempted to betray them and was punished with fear toxin. After confronting Scarecrow and interrogating Stagg, Batman is again exposed to the toxin, triggering intense hallucinations. Scarecrow flees with the Cloudburst. Batman receives a message from Scarecrow indicating Barbara is in the same location where Ivy was held. Before he can reach her, Barbara is doused with the toxin and fatally shoots herself. Batman and Alfred Pennyworth are heartbroken, but Alfred urges Batman to remain strong for Barbara's sake. Alfred explains that the Cloudburst is a device meant to spread the fear toxin across Gotham. To stop it, Batman enlists Ivy, who uses a massive tree to grow giant flowers capable of neutralizing the toxin.
