The Mad Hatter has escaped from prison, and is on a quest to add Batman's cowl to his collection of hats. He attends Gotham City's annual headdress ball disguised as the Three-tailed Pasha Of Panchagorum, and snatches a large ruby off of columnist Hattie Hatfield's headdress. The villain makes a getaway, but not before turning Batman's cowl pink with a radioactive spray. He trails Batman to the Atomic Energy Laboratory, knowing he will have a chance to snatch his cowl when it is removed for decontamination.
