At Wayne Manor, Bruce Wayne and Dick Grayson watch their favorite show, Gotham Palace. During the programming, a band that was supposed to play on the show is revealed to be hidden and replaced by the Joker, the Penguin, the Riddler, and Catwoman. Bruce and Dick suit up as Batman and Robin and head to the Gotham City Police Department, where they receive a riddle from Commissioner Gordon and Chief O'Hara.

They discover that the villains are robbing the Acme Atomic Energy Laboratory of the Replication Ray, which can duplicate anything. After a brief fight, the criminals manage to escape Batman, but leave behind a clue that leads Batman and Robin to their lair in an abandoned TV dinner factory. While discussing what to do with the Replication Ray, Catwoman reveals her plan to make Batman join their side with a scratch from a substance called "Batnip". After Batman and Robin break in, they are defeated by the criminals and trapped on a frozen food tray heading towards a large oven. Catwoman uses her Batnip on Batman, but he is seemingly unaffected by it. The two escape the trap after the villains leave the factory.

Back at Wayne Manor, Bruce starts showing signs of aggression after Harriet Cooper nearly discovers the Batcave. He blames Alfred Pennyworth for the incident and fires him, leaving the butler to wander on the streets homeless. After days of not finding Joker, Penguin, Riddler, and Catwoman, Batman deduces that the four are no longer on Earth and have hijacked a space station. He and Robin go into space with the help of their Bat-Rocket. At the space station, Joker, Penguin, and Riddler betray Catwoman, distrusting her due to her feelings for Batman. They try to throw her out into space, but she is rescued by Batman and Robin and aids them in defeating her former allies for revenge. Batman savagely beats the three men and recovers the Replication Ray, but Catwoman escapes in an escape pod in the process.

After the mission, Dick expresses concern towards Bruce's increasingly hostile behavior. Bruce ejects Dick from the manor and takes a break from being Batman, resulting in a crime spree in Gotham City. A few weeks later, Batman returns to the Gotham City Police Department and blames the police for the increase in crime. He uses the Replication Ray on himself to replace most of the jobs, citizens, and political figures in Gotham with his replicas, planning to take over the world. Dick, realizing that the Batnip had a delayed effect on Batman, goes to Catwoman's lair as Robin to request her help in curing Batman. She agrees, as the effects of the Batnip were more severe than she had planned.

The two take the Catmobile to the Batcave, where Catwoman attempts to give Batman the antidote. Having anticipated this, Batman reveals that he took the Bat Anti-Antidote, nullifying Catwoman's antidote. Batman defeats the two in a fight and leaves them to die in the Atomic Pile, but they survive thanks to Robin's Bat Anti-Isotope Spray. Knowing they cannot take on an army of Batmen by themselves, Robin and Catwoman disguise themselves as prison inspectors and break most of Batman's rogues gallery from Gotham State Penitentiary by claiming to Warden Crichton that the ball and chains and pickaxes are not in good shape, replacing them with versions that carry the villains out of the prison. While a prison guard tells Crichton that Joker, Penguin, and Riddler did not escape, the three of them mysteriously turn into a pile of dust.

The two confront Batman and his army on the Gotham Palace set, but they still lose even with the help of the criminals. Before Batman is able to kill Robin and Catwoman, a disguised Alfred arrives and gives Batman a celebratory bottle of champagne laced with a strong enough antidote to counter the Bat Anti-Antidote. Batman returns to normal, and his clones turn to dust as the Replication Ray was not strong enough to make perfect clones. Batman and Robin then realize that Joker, Penguin, and Riddler tricked them by having them arrest copies of them while the real ones have been robbing the city blind, using Batman's behavior change as a distraction from their crime spree, knowing the Batnip would work as they spiked it with Joker's Laughing Gas formula to make it more potent. After catching them robbing the Gotham Art Museum, Batman, Robin, and Catwoman (as vengeance for what they did to her at the space station) chase them to Penguin's blimp, where the villainous trio are defeated after getting knocked off the blimp and falling to a safe location to be arrested. Catwoman tries to escape with the stolen loot, but Batman stops her. Unwilling to be imprisoned, Catwoman allows herself to fall into a smokestack.

Bruce and Dick then throw Harriet a surprise birthday party, acting as if that is the secret they have been hiding from her. During the party, Bruce and Dick are called away by the Bat-Signal.
