On one very dark night in Gotham City, the Joker has been mysteriously released from Arkham Asylum, and he's none too happy about what's happened to his city rackets while he's been "away." What follows is a harrowing night of revenge, murder and manic crime as only The Joker can deliver it, as he brutally takes back his stolen assets from The Penguin, The Riddler, Two-Face, Killer Croc and, of course, The Batman.
