A former academic who thinks he is really King Tut has returned. Batman and Robin seek his capture. A twist occurs, however, when King Tut's gang kidnaps Bruce Wayne. They are taking the millionaire in an ambulance. As Bruce tries to get free, the rear doors of the ambulance open and Bruce rides a cart toward a cliff.

Bruce frees himself just before the cart he is riding goes over a cliff. As Batman, he works to bring King Tut to justice. But the hero is captured by King Tut instead. Batman is then tortured as King Tut drops a pebble on his head at a time. Robin works to track Batman in time.

King Tut has relapsed into his kingly ways, this time showing a marked interest in scarab beetles and apothecary potions. Robin infiltrates their hideout to discover their true intentions, relaying what he hears to Batman, but their plan is put in jeopardy when Robin's presence is detected.

Using resurrected scarab beetles, King Tut concocts an ancient mind control potion, abu raubu simbu tu. Chief O'Hara is the first under his spell, followed shortly by Commissioner Gordon, and when Batman himself is tricked into taking the drug, Tut's plan to control all of Gotham City by tainting the water supply seems close to succeeding.

After a blow to the head, Yale's Egyptology professor once again believes he is King Tut. He mistakes Bruce Wayne's friend Lisa for Queen Cleopatra, and kidnaps her so he can bring her to Egypt as his bride. Batman and Robin soon locate Tut's hideout, thanks to a hidden tracking device. But soon after entering, they are captured by Tut's cronies, and Batman is submerged in a sarcophagus under five feet of water.

Though Batman escapes his watery trap, Robin is left in the hands of King Tut. The deluded villain still believes that Lisa Carson is really Queen Cleopatra, and calls Lisa's father to demand a ransom of $8,300,487.12, the mortgage on the Pyramids. Using the Jolly Jackson radio show to communicate, Tut negotiates the terms of payment with Batman. However, the villain most likely intends to keep both the money and Lisa, and has further plans to fry the Caped Crusaders in his royal boiling oil.

The Penguin steals a priceless folio of famous parasols from the Gotham City Library. He plans to wager the $10,000 earned from its ransom on a rigged horse race. Aided by his partner-in-crime Lola Lasagne, he disguises the favored entry Parasol as the unknown "Bumbershoot," then enters a painted glue factory horse as "Parasol". With everyone betting their money on the fake horse, it looks like the Penguin will make a fortune when the real Parasol wins the race. But he wasn't counting on a last-minute entry of Bruce Wayne's, the horse Waynebow, ridden by none other than Batgirl.

King Tut has been predicting crimes, then secretly making sure they happen in order to gain the police's confidence. He hopes to then send them on a false lead while he commits the crime of the century. After failing an attempt to discover Batman's true identity, he gives his biggest prediction - a jailbreak of several super criminals. While the entire police force is sent to the penitentiary, Tut nabs a collection of priceless Egyptian scrolls from the Gotham City Library. The scrolls contain the key to an ancient statue, rumored to give its possessor control of the universe.

After his previous battle with the Terrific Trio, Shame now has Batgirl as a hostage. He agrees to a swap when he realizes that Batman and Robin also have Calamity Jan's mother, Frontier Fanny. Batgirl informs the Dynamic Duo of a plan for a "great train robbery" that she overheard as a hostage. The three work to figure out Shame's plan and race to stop him. But when they realize they are too late, Batman attempts to lure him out of hiding with an offer of man-to-man combat.

With plans to build an indestructible empire, King Tut goes in search of Nilanium, the world's strongest metal. But with the only known deposit lying directly beneath Wayne Manor, Tut's tunneling soon leads him to the discovery of a lifetime - the Batcave itself. With their secret identities in jeopardy, Batman and Robin race to stop him before his find is leaked to the world.
