Synopsis:
After crash-landing the Bat-Plane in the African jungle, Batman and Robin are captured by aliens to be specimens for an alien circus. Batman tries to prove to the aliens that he is intelligent, but the aliens do not understand.

Batman then learns that the circus is being used as a training ground for criminal robberies using the alien animals. He and Robin escape confinement. They flee the circus while being pursued by alien authorities. Batman finally proves his intelligence to the aliens and exposes the criminal organization. He and Robin are rewarded by being returned to Earth.
