What happens when Gotham City's Clown Prince of Crime discovers a thousand-year-old relic that will make him invincible? Unfortunately, Batman is about to find out, as two of history's most madcap maniacs join forces -- literally! And to add insult to injury, Joker/Mask becomes a prime-time television sensation, and you don't want to know how far he'll go to keep his ratings high! Joker/Mask is more fun than a barrel of monkeys -- monkeys with hand grenades, that is!
