Someone's hired Catwoman to retrieve a computer chip from the lion's cage and take it to another exhibit. There she learns her contact is... The Joker! Using a pair of pies, he coats her with a chemical mixture containing "tagyurit" that's radioactive and doesn't wash off, so he can find her wherever she goes. She thinks it's a joke, until missiles start tracking her. Missiles keep tracking; finally, she escapes through a river and finds a flop hotel - she can't go home. But the Joker finds her there and sets the place on fire! Why is he suddenly interested, and when will he stop? Until Catwoman can learn the answers, she'll have to keep moving: it's dangerous to be near her!
