An urgent cry for help sends Scooby and the gang rushing to Gotham City-but the call was made by Harley Quinn and Poison Ivy! They stole an ancient relic, and now they\'re sure it was cursed. Our heroes have to join Harley and Ivy to get to the bottom of the mystery-and, with a little help from Batgirl, they just might capture the villains, too!\"(W) Sholly Fisch (A/CA) Dario Brizuela
