Batman is personally delivering his nemesis, The Joker, to the asylum at Arkham Island, but he is uneasy. Although the Arkham asylum is well fortified, he has a nagging feeling that all is not well, which proves to be the case when seconds after turning The Joker over to the guards, the master criminal breaks free of his captors. Even more surprising than this quick turn of events is the revelation that it was never The Joker’s intent to escape the vault-like facility, but instead to trap Batman there. Surrounded by an asylum full of dangerous criminals, many of which he put there and all at the beck and call of the Joker, can Batman survive and discover what is behind the Joker’s intricate plot?
