Professor Potter drops off his new invention, the Maniac computer, at Lois Lane’s apartment. The computer is a brain machine that can answer any question put to it. Lois uses the machine to get a scoop and a raise at work. Then she aks the machine how to get Superman to marry her. It prints the instructions for her, then Lana tries to use the machine for the same purpose. Lois sabotages the machine and rushes off to meet Superman; instead she finds Clark Kent. The instructions get lost, though Superman later finds them and learns that the machine correctly predicted his secret identity.
