The Joker is one of the most dangerous villains alive. But what if he were cured of his madness? Would he also be cured of his evil nature, or would his evil finally be given free reign? The Batman discovers to his horror that it’s the latter when the Joker uses Ra’s al Ghul’s resources to hijack a communications satellite, causing the world’s computer systems to speak to each other in random languages. With the clock ticking down to world catastrophe, Batman must stop the Joker’s plans before it’s too late. Guest starring Catwoman!
