Summary:

Captain James Gordon and other officers are investigating a building filled with mutilated corpses. Batman enters and converses with Gordon. Next, Bruce Wayne is seen at a social event talking to fellow millionaire Henry Claridge. On a TV in the next room, a reporter is overheard announcing that Arkham Asylum is being reopened. She suddenly begins laughing and soon dies with a face similar to the mutilated corpses at the building. The Joker (who has not yet been given the name the media bestowed upon him) walks onto camera and announces he will kill Claridge at midnight.
