The mighty Despero, one of the greatest threats our world has ever known, sits in his stronghold high in the Rocky Mountains, planning his conquest of the earth! But Batman has uncovered the would-be tyrant's scheme, and now the Dark Knight has assembled a squad of heroes to infiltrate the villain's lair. The team include Robin, Green Arrow, Aquaman, and Hawkman - each an expert in hand-to-hand combat, each noted for his incredible stealth. Batman has also altered each hero's costume with a special light-refracting coating, giving them an edge over Despero's high-tech security devices. Now it's up to these five heroes to stop Despero - before it's too late!
