When Batman and Robin get a tip that Commodore Schmidlapp is in danger aboard his yacht, they launch a rescue mission using the Batcopter. After a tangle with an exploding shark, Batman and Robin head back to Commissioner Gordon’s office where, through deduction and wisdom, they figure out that the tip was a set-up by four of the most powerful villains ever (Joker, Penguin, Riddler and Catwoman), who have united to defeat The Dynamic Duo once and for all. Armed with a dehydrator that can turn humans into dust the “fearsome foursome” intend to take over the world, and Batman and Robin must stop them. (thetvdb.com)
