Robin deactivates the hot-air balloon's altimeter with a piece of chewing gum that was dropped in the basket by one of Puzzler's men just scant seconds before it manages to reach 20,000 feet. Utilizing a bird call, The Boy Wonder then attracts an elusive and high flying giant red-eyed hermit nuthatch bird migrating south for the winter. The bird pecks a hole in the balloon, allowing it to descend safely to earth next to an emergency public telephone booth.
The Dynamic Duo returns to The Puzzler's factory where Puzzler distracts them long enough for himself and his cronies to scram. Puzzler continues his quest to seize Knab's supersonic plane, the Retsoor, sending his sexy moll Rocket to drug Knab's tea while Puzzler himself photographs the secret plans for the hi-tech jet. The Caped Crusaders are alerted to The Puzzler's new target by way of a rooster sent to Gordon's office. Batman and Robin speed to the Retsoor's hangar, have a tense Batbattle where the entire gang is captured and the theft of the Retsoor prevented. Bruce and Dick end by having fun with Puzzler's puzzle balloons with Harriet and Alfred.
