Synopsis:
Superman summons Batman to Metropolis to help learn the identity of a prankster who is announcing Superman’s secret identity. The clues point to Lois Lane or Perry White, but neither Batman nor Superman think they are responsible. Batman eventually determines that Superman himself is the culprit. He staged the hoax in order to get Batman out of Gotham, so that he could impersonate the Caped Crusader and take down the Varrel Mob.
