Synopsis:
Superman and Batman compete in a contest to determine which whether Gotham City or Metropolis will host a science convention. Superman patrols Gotham and performs four feats in the allotted time frame. Batman is able to perform five feat in Metropolis, earning him the victory for Gotham City.

Batman tried hard to win the contest because one of the inventions on display at the convention emits Kryptonite rays. When the machine is tested, Superman is nearby and weakened. However, the machine malfunctions and destroys itself. Superman then reveals he performed a fifth feat, so the convention is held in both cities.
