Synopsis: Henry Lewis is a millionaire who uses his wealth to indulge a passion for surveying. He stumbles across a series of limestone caverns that lead directly beneath Fort Stox, one of America's gold
reserve locations. Renoldo, leader of a criminal gang, hears of the cavern but not its location, so he leads Henry's daughter Linda to believe she's killed
a man and then blackmails her into revealing the location. Upon learning of the scheme, Batman and Robin race the criminals to the caverns and
apprehend them before they can rob the gold.
