Batman

Batman and Robin receive a tip that Commodore Schmidlapp is in danger aboard his yacht. They launch a rescue by the Batcopter and race toward the vessel to intervene. The chase sets the stakes high as they prepare to reach the scene.

Batman descends to land on the yacht, but the vessel vanishes beneath him. He falls into the sea and is attacked by a shark. He uses bat-shark repellent to drive off the creature, which explodes at close range.

Batman and Robin head back to Commissioner Gordon's office to review the situation. They deduce that the tip was a setup by the United Underworld, a coalition of criminals. This realization shifts their focus to stopping the mastermind group.

The Joker, Penguin, Riddler, and Catwoman build a plan using a dehydrator that turns people into dust until they are rehydrated, an invention of Schmidlapp's. They escape in a war-surplus, pre-atomic submarine made to resemble a penguin, and recruit three pirate-themed henchmen: Bluebeard, Morgan, and Quetch. This alliance marks the rising threat Batman and Robin must counter.

Batman and Robin learn the yacht was actually a holographic projection. They return by Batboat to a buoy concealing a projector and are trapped on the buoy by a magnet as torpedoes close in. They improvise to survive the deadly setup.

Two torpedoes are destroyed by Batman and Robin using a radio-detonator. A porpoise sacrifices itself to intercept the last torpedo, buying the heroes time to escape. The peril of their pursuers becomes increasingly evident.

Catwoman, disguised as Kitka, helps the group kidnap Bruce Wayne and pretends to be kidnapped with him to lure Batman. The plan is to finish him off with one of Penguin's explosive animals, unaware that Bruce is Batman. The deception adds personal risk to the mission.

Bruce Wayne fights his way out of captivity and returns in his Batman form. The Dynamic Duo infiltrates the United Underworld's HQ and finds a smoking bomb. The counterstrike against the criminals begins in earnest.

The Penguin disguises himself as the Commodore and enters the Batcave with five dehydrated henchmen. The plan fails when the henchmen dissolve into antimatter after rehydration with toxic heavy water used to recharge the Batcave's reactor. The dangerous flaw exposes the fragility of their sabotage.

Batman and Robin are unable to prevent the kidnapping of the dehydrated United World Organization's Security Council. They pursue them in the Batboat to retrieve the ambassadors and Miss Kitka. The stakes rise as the world watches the crisis unfold.

Robin uses a sonic charge to disable the Penguin's submarine and force it to surface. A fist fight ensues on the water as Batman and Robin prevail. The victory tightens the net around the criminal alliance.

Batman discovers that Miss Kitka is actually Catwoman when she loses her mask during the confrontation. The revelation compounds his heartbreak and muddies the lines between ally and adversary. The romantic tension adds a personal twist to the showdown.

Schmidlapp sneezes on the powdered dust, scattering the Council members into dust. Batman constructs a Super Molecular Dust Separator to filter the mingled dust and restore the Council. The technical fix becomes a central tool in resolving the international crisis.

Robin suggests altering the dust to prevent harm in the future. Batman refuses, citing the fate of the Penguin's rehydrated henchmen and the need for people to live together. His stance underscores a belief in human choice over technological control.

The Security Council members are hydrated again, alive and well, but now exhibit accents and mannerisms of other nations. Batman hopes the mind-melding will do more good than harm, and he and Robin escape through a window using bat-ropes. The mission ends with a cautious note about global diplomacy and peace.
