The Dynamic Duo witnesses the destruction of a robot on the streets of Gotham City by a man calling himself Mr. X. They track Mr. X to a boat where they are attacked by a sea creature. Mr. X appears to rescue them. The man escapes leaving Batman puzzled.

Two riderless horses arrive with a letter for Batman. The horses take Batman and Robin to a castle filled with gorillas. Batman is forced to swordfight one of them. Batman overcomes his opponent, and Bat-Mite reveals himself. All the creatures, including Mr. X were created by the imp to challenge Batman. Batman scolds Bat-Mite, who returns to his own dimension which causes everything he created to disappear.
