Synopsis:
Superman and the Dynamic Duo encounter an injured man dressed as Humpty Dumpty. They take the man to a doctor, but both the man and doctor disappear leaving behind a clue relating another Mother Goose Nursury Rhyme.

The heroes are led to a replica of London Bridge where more strange happenings occur and they locate more clues. Puzzled after following the clues to yet another location, they decide to backtrack to learn the secret to the mystery.

The scenes were designed by a group called Adventure Inc. The purpose is to entertain rich men, but their clients who were supposed to play the parts of Superman, Batman, and Robin confused the dates and the real heroes unknowingly took part instead.

A small-time hood gets involved, believing he can cash in on the events. At the next scene, he commits a robbery. The heroes intervene and stop him, which leads to Adventure Inc. finally learning that it is the real heroes and not their clients participating. The mystery is explained and the hoods are captured.
