Gotham City is literally held in the grip of terror by The Scarecrow's arsenal of Fear Transmitters. Scouring Gotham in search of Scarecrow, Batman is himself paralyzed with fright when he finds himself in the middle of Crime Alley, where years earlier the parents of Batman's alter ego Bruce Wayne had been murdered in cold blood. Taking advantage of the situation, Scarecrow intends to keep Batman trapped in Crime Alley forever by using a captured Robin and Wonder Woman as bait—forcing the Caped Crusader to purge himself of his lifelong fears once and for all!
