As luck would have it, a well-timed solar eclipse ocurs just as the sun is about to barbecue our heroes. They shift the magnifying glasses with their feet so that the returning sun will now burn off their bonds. Back at The Batcave, The Dynamic Duo deduce The Catwoman's next objective, and rush to The Gotham State Building and discover a momentous sale of Zubin Zucchini's 2 rare stradivarius violins for $250,000 each is to occur on the 102nd floor. See, The Gotham State Building's 102nd floor is the only place in Gotham City with the proper altitude and humidity to inspect the violins, which haven't been out of their cases in 30 years and might crack in the improper atmosphere, and The Catwoman covets them for the 8 pieces of catgut (good grief!) attatched to them! Meanwhile, The Foul Feline has overcome rich old recluse Minerva Mathews with gas and, disguised as Matthews, replaces her as the purchaser of the violins. The incognito Catwoman goes to the 102nd floor, disabling the elevators behind her and greedily trying to snatch the 2 violins from Zucchini, only to find that he is actually Robin in disguise! He is immediately overpowered by Catmen John, Charles, and Thomas, and crooked gossip columnist Jack O'Shea, who reveals their mode of escape: a getaway rocket!

On the first floor, Batman, on learning Catwoman has disabled the elevators, attatches his new Batjets to one of the stalled elevators; the thrust is enough to send The Caped Crusader and the elevator to the top floor in no time. He arrives in time to rescue the outnumbered Boy Wonder, just as he is about to be tossed out the window by O'Shea and The Catmen. The Duo dispose of the men, and Batman finds Catwoman (after experiencing mechanical problems with the getaway rocket during the fight) outside on the ledge, attempting a getaway with the money and violins, of course, but is impaired by vertigo! Batman secures one end of his Batrope, tosses the other end to a frightened Catwoman, and tells her to drop the (obviously fake!) violins and money and tie thr rope around her waist. Suddenly O'Shea recovers and shoves Batman out the window! The Boy Wonder sends O'Shea back into dreamland with a generous right cross and, finding The Caped Crusader has grabbed hold of his Batrope and he and Catwoman are hanging onto each other for dear life, single-handedly pulls them to safety. In Gordon's office, prior to her being taken to the pen, Catwoman rewards Batman with a simple rub on the cheek.
