The Penguin plots to manipulate Batman into inadvertently devising capers for him.

Bruce Wayne escapes the Penguin's deathtrap and returns to the Batcave. What he doesn't know is that one of the Penguin's clues, an umbrella, has a listening device.

The Dynamic Duo arrange a trap for an elusive annual bank robber, but the female magician they are hunting is on to them with a new scheme of her own.

Told that her loot is genuine money after all, Zelda is forced to lure Batman and Robin into a possibly unsolvable deathtrap, with hitmen waiting outside to shoot them if they escape.

At Woodrow Roosevelt High School, a vending machine gives out money. Dick Grayson is there to witness it. Batman learns the vending machines are operated by a company bought by the Joker after being released from prison. The Joker and his gang are aided by Susie, a cheerleader at the school. In the course of their investigation, Batman and Robin are captured and placed in electric chairs. If a "one armed bandit" comes up the wrong way, they'll be electrocuted.

A power failure prevents Batman and Robin from being electrocuted. Meanwhile, a recording Batman made confirms that cheerleader Susie is one of the Joker's confederates. Robin, in his Dick Grayson identity, attempts to infiltrate the gang. Meanwhile, the Joker's main plot is finally revealed. Members of the high school basketball team receive answers to final exams from the rigged vending machines. The Joker appears, claiming to be a concerned citizen. The team's starters will be suspended as the Joker bets big money on the team's next opponent. Batman, however, has other ideas.

After his recent release from jail, The Penguin has started his own protective agency and is thwarting small time hoodlums everywhere he goes. Batman & Robin decide to send in an undercover Alfred to spy on the newly reformed Penguin and his recently acquainted high society friends. However, the Penguin has anticipated Batman and Robin's every move and manages to give them a makeover into wanted men instead of him.

Already wanted for a robbery they didn't commit, Batman and Robin fake their own deaths with a little help from Commissioner Gordon and Chief O'Hara. They even allow the Penguin to take hold of the Batmobile, now renamed 'Birdmobile' in order to keep track on them via a hidden camera.

Chandell, the musical virtuoso, visits Gotham City for a piano concert. But unknown to the public, Chandell is being blackmailed into a life of crime by his twin brother Harry, who retains most of the profits. Chandell intends to buy off Harry forever, and he knows just where to get the funds - from the Wayne family fortune. With Batman and Robin out of town, he suspects the robbery will be a piece of cake. However, Batman has been listening to Chandell's concert remotely, and after detecting an anomalous chord, summons Robin back to Wayne Manor to investigate.

Batman and Robin escape Chandell's trap. Once back in the Batcave, they deduce his plan to get the Wayne family fortune by killing Bruce Wayne and Dick Grayson, then marrying the rightful heir, Aunt Harriet. In order to trap the villain, Bruce and Dick fake their own deaths. However, Harry has also figured out his brother Chandell's scheme, and desiring the Wayne fortune for himself, concocts a plan to masquerade as his twin brother.

Penguin has opened a fancy restaurant called The Penguin's Nest. There every order has to be written down by the customers on a piece of paper. He then plans to get himself arrested and hand over the handwritten notes to a forger doing time by the name of Ballpoint Baxter. Suspecting a scheme, Batman urges the police not to send The Penguin back to his permanent cell. Unable to reach Ballpoint, The Penguin and his culinary cohorts escape from jail, taking Chief O'Hara along as a hostage.

Attempting to save Chief O'Hara from drowning inside a metal trunk, Batman and Robin find themselves under fire from the Penguin's henchmen. Batman instructs Alfred to pose as famous forger Quill-Pen Quertch (complete with false fingerprints), but the Penguin recognizes Alfred as soon as he puts on his glasses. The evil Bird-man and his cronies then visit stately Wayne manor brandishing a giant Butler-pie.

Counterfeit money is being distributed by respectable citizens in Gotham City. Batman and Robin investigate, and find one of the Joker's lifelike robots substituting for a bank teller. They are certain who is behind the crime. But to get actual proof, Batman plans to visit the villain as Bruce Wayne and trick him into disclosing his operation. When his scheme suddenly backfires, it appears he will instead have to appoint the Joker as Vice Chairman of the Gotham National Bank.

The Joker is now Vice Chairman of the Gotham National Bank, due to an unsuccessful plan of Batman's. He installs his robots as tellers, and despite his criminal past, seems to be running things in perfect order. The Dynamic Duo realize they will have to trick him into making a mistake in order to remove him. They go to work on a plan to gain control of his robots. But that plan is jeopardized when, due to an odd turn of events, Batman's true identity Bruce Wayne is declared mentally ill and hauled off in a straight-jacket.
