Synopsis:
Batman and Robin tail a wanted criminal aboard a ferry. Due to strange atmospheric conditions, the ferry is transported to another dimension. The crook, Eddie Stark, escapes into the jungle, while Batman and the other passengers are captured by a race called the Yllans.

The Yllans accuse the Earthmen of being evil. Before, they can be convinced otherwise, their archenemies, the Gruggs, attack. Batman helps fend them off, but Stark steals the Yllan weapon that can defeat the Gruggs.

Batman and Robin search for Stark while the others are held captive. Stark uses the weapon, a tele-dome, to command the Gruggs into attacking Batman. Robin must rescue him and together they use the pollen from a plant to cause Stark to sneeze a lot. The Dynamic Duo is able to capture Stark and return the Yllan weapon. The humans are then allowed to return home.
