Batman and Robin get back on the Penguin and Marsha, Queen of Diamonds', trail. Several escaped lizards lead them to the villains' hideout, where they find the stolen chain mail suits. Remembering an earlier clue from the Penguin, they head to the federal subtreasury to find that the Penguin, Marsha, and their cronies have broken into a vault containing ten million dollars in gold bullion. The Dynamic Duo shut the vault door on the criminals and try to prepare for every breakout scenario, but the Penguin has a daring plan of escape that no one could have counted on.
