Synopsis:
Batman uses a flying spy eye to observe crooks planning a crime. The crooks mention that one of Batman's own inventions will be used in the robbery. Batman and Robin recall several previous cases, trying to determine which invention might have been stolen. They rule out nearly every invention except the spy eye itself. They realize that criminal scientist Curt Mathis must have taken x-ray photos of the eye when Batman used it to catch him. Once the Caped Crusaders learn which invention will be used, they are able to stop Mathis and prevent the robbery.
