Synopsis:
While attempting to apprehend a gang of safe-crackers, Batman and Robin are surprised by the Blockbuster. While Robin deals with the crooks, Batman exposes his unmasked face of Bruce Wayne to calm Blockbuster. Somehow Batman's mask returns to his face. Enraged by Batman's appearance, Blockbuster attacks him. Batman manages to duplicate the voice of Roland Desmond to scare off his foe.

To prevent the unexplained problem with his mask from happening again, Batman paints the mask with special make-up that will make it transparent under special lighting. When Blockbuster appears again, Robin shines the light on Batman's mask, allowing his features, now made up to resemble Roland Desmond, to appear.

However, Robin is knocked unconscious by flying debris. Without the light, Batman's mask returns to normal, and Blockbuster defeats him. Blockbuster's hidden accomplice the Outsider then places Batman in a trap. However, Blockbuster turns on the Outsider. Batman escapes his trap and finally defeats Blockbuster. The Outsider escapes without Batman learning of his involvement.
