Batman tries to find out who the new mob boss in town might be, and discovers that the Penguin has extended his influence, controlling a crime family covering a quarter of the city. What Batman doesn't now is that Penguin is working with the Scarecrow and Linda Friitawa, an albino geneticist. As Batman continues his investigations, a group of mob bosses, on their way to meet with the Penguin, come under attack from what looks like a monstrous version of the Scarecrow.
