The Joker appears in an art gallery and defaces the paintings with paint-spraying guns. But instead of being horrified at his alterations, the Joker's work is praised as "art". After more success at an international art competition, the Joker founds his own art school. But Batman and Robin suspect he has a more sinister purpose in mind when he enrolls only wealthy millionaires.
