Synopsis:
The mayor orders Commissioner Gordon to call in Batman to help stop a gang of smugglers. Batman enlists the aid of a costumed hero, Mysteryman to assist against the smugglers. Vicki Vale wonders why Batman needs assistance and sets out to learn Mysteryman’s identity. First Vicki believes the new hero is a robot; then she thinks it is Superman. Eventually she learns that Mysteryman is Commissioner Gordon. Gordon had been working on the smuggling case, but didn’t want to disregard the mayor’s order to turn it over to Batman. With the smugglers captured, Vicki announces her discovery which Batman intended.
