Philanthropic entrepreneur Bruce Wayne (Adam West) and his youthful ward Dick Grayson (Burt Ward) lead a double life: they are the Caped Crusaders, crime-fighting duo Batman and Robin. A secret Batpole in the Wayne mansion leads to the Batcave, where Police Commissioner Gordon calls the fearless duo on the Batphone with the latest emergency threatening Gotham City. Racing to the scene of the crime in the Batmobile, Batman and Robin must (with the help of trusty Bat-Gadgets) thwart the efforts of a variety of master criminals.

The dastardly deeds begin when The Penguin (Burgess Meredith) uses his flipper-powered submarine to steal a super-dehydrator, which extracts all moisture from humans and reduces them to particles of dust. But the Antarctic Anarchist is not working alone, gentle reader! No, a plot this size requires the combined evil thinking caps of four costumed criminals: The Penguin himself, The Riddler (Frank Gorshin), The Joker (Cesar Romero) and Catwoman (Lee Meriwether). And as Commissioner Gordon (Neil Hamilton) puts it, "The sum of the angles of that rectangle is too monstrous to contemplate!"

Using the super dehydrator, the United Underworld (as they dub themselves) suck the moisture out of the nine-member United Nations Security Council, leaving nine multicolored piles of dust. Can no one stop this blueprint of badness? This design of devilry? Two men can (well, one man and one boy wonder) with the help of their trusty butler Alfred (Alan Napier). But first they'll have to defeat a ticking time bomb, an exploding octopus, and a shark with a six-foot vertical leap.

Can the Dynamic Duo stop the fearsome foursome in time? Will Bruce Wayne fall under the spell of lovely Miss Kitka, exotic correspondent for the Moscow Bugle, who happens to be Catwoman in disguise? Can the man-eating shark be stopped with Batman's Shark-Repellent Bat-Spray? Will Commissioner Gordon decipher the Riddler's criminal conundrums?
