Paging the Crime Doctor

A lone armored truck drives the night streets of Gotham. An ambulance drives up behind it and the drivers pull over. However, the ambulance drivers pull out a gun and blow out the truck's tires. They then hurl a gas bomb into the truck causing the drivers to pass out and crash. A trio of criminals crawls out of the ambulance and steal its cargo. They muse over how easy the job was but Batman comes to disillusion them of that notion. The crooks put up a fight but Batman manages to force them to crash and proceeds to apprehend them. However, one of the criminals takes hold of the stolen cargo: a surgical laser, and fires it at Batman. Batman's cowl is grazed and though the laser malfunctions, Batman is thrown off balance just long enough for the crooks to throw him from the bridge. They believe Batman is dead, but he luckily managed to land on a trolley car and escapes.

The thugs run off to Rupert Thorne who is going to see a doctor, Matthew Thorne, who specializes in helping criminals. Rupert is skeptical that his thugs managed to kill Batman but he's got other things to think about. He gives Matthew the medical laser but Matthew is upset. Rupert mentions how they're brothers and he thinks that there is no reason for the contempt. However, Matthew relates on how he failed to report a bullet (as is required by law) that he removed from Rupert on his insistence and for that he lost his license. Rupert is unsympathetic and starts yelling at Matthew but he starts having heart problems and falls to the ground.

Meanwhile, Leslie Thompkins treats a few patients and is visited by Batman. Batman falls to the ground in front of her and she diagnoses him with a concussion. She prescribes him some medicine and tells him to stay in bed the whole day but she knows that he won't and reminisces on how Thomas knew Bruce was stubborn too.

Matthew takes some x-rays of Rupert and explains that he has a heart tumor that's pressing against the aorta and restricts the flow of blood into the heart. He tells Rupert that the only way that he can save him is to take him to the hospital but Rupert refuses. Not wanting to see his brother die and eager to recover his license (which Rupert promises him if he helps) Matthew talks about Leslie Thompkins whom can help him. Rupert sends his thugs over but Matthew insists on going with them.

Rupert's thugs go to retrieve Leslie who knows about Matthew's criminal activities. She refuses to help save Rupert and Matthew allows the thugs to take her by force.

Back at Rupert's hideout, Leslie and Matthew prepare for the surgery. Leslie is skeptical that Matthew will really get his license back but Matthew is sure his brother won't turn on him. Meanwhile, Batman checks a fabric sample and learns that the thugs were working for Rupert Thorne and wonders why he would want a surgical laser. Deciding to pay Leslie a visit, he and Alfred find the entire place in shambles. Searching the room, they find a picture of Leslie and Thomas when they were still in medical school. Reading the message on the back, "Thanks for all the good times with my two Best Friends. Love, Matt." Alfred remembers that Matthew was a colleague in medical school. Bruce looks up the school's yearbook and finds Matthew Thorne's picture. Realizing the connection to Rupert, he deduces where Leslie is.

The operation a success, Matthew and Leslie leave the operating room. Unfortunately, Rupert had left his thugs with orders to kill Leslie once the operation was over. Batman arrives outside of the building but one of the orderlies catches him and attacks. Batman is still suffering from his concussion and finds it difficult to fight the orderly. Things only get worse when the orderly manages to get hold of the surgical laser and starts firing on him. Fortunately, Batman manages to beat him.

While Batman deals with the orderly, Matthew wants to leave Leslie alive and take her home but the thugs say that if he interferes with them killing Leslie the deal is off. Matthew agrees to let Leslie die but says he wants it done his way: he'll give her an injection which will be quick, painless, and can be made to look like she died of a heart attack. Leslie is unsurprised at the fact that she'll be killed and disgustedly calls Matthew no better than his brother. However, Matthew sticks Rupert's thug with the injection causing him to pass out. Matthew then tells Leslie that they have to leave. She's surprised that Matthew sided with her but he says that his license isn't worth a person's life. Leslie's relived believing that Matthew is back to his old self. Unfortunately, the thug is discovered by another thug and he calls for help. Matthew and Leslie make their way up the elevator to the roof of the building while Batman arrives and handles the thugs. Unfortunately, one of them manages to get into an elevator and onto the roof.

On the roof, Matthew manages to jump to the next rooftop but Leslie isn't sure she can and only leaps after the thug starts firing at her. She jumps but was right about not being able to make it and just barely manages to grab onto the edge. Matthew tries to hold her up but the thug gets ready to shoot. Fortunately, Batman stops him. Unfortunately, Matthew is unable to hold onto Leslie and she drops. Batman, however, is able to save her before she hits the ground.

Later, Matthew is in jail and receives a visit from Bruce who is willing to help with the legal costs and put in a good word. Matthew is skeptical about Bruce's intentions however, and when he learns that Bruce wants something he promptly refuses. Bruce tells him that he doesn't want anything illegal. When asked what, Bruce replies, "Something you know. Something only you can give me. Tell me about my father." Matthew is only too willing to comply.

It's Never Too Late

In his estate, Arnold Stromwell, Gotham's reigning crime boss, is watching the evening news. The lead item is the worsening conflict between himself and upcoming boss Rupert Thorne. That much he knows, but he is shocked to hear on the news that his son, Joey, has been missing for days. He and his son were estranged, but Stromwell is convinced that Thorne is behind this. He orders his men to set up a meeting with Thorne.

Batman, disguised as a hobo is eavesdropping on Thorne when he receives Stromwell's message, and plots to assassinate Stromwell. On the way to the meeting, Stromwell passes an old rail yard, and has a flashback: two young boys, Arnie and Michael, are arguing on their way home. Arnie has stolen a handful of candy, and Michael refuses to take any. Arnie swears that one day he will "own" Gotham. But as they walk home, a train roars up the tracks at the boys. Michael dives out of the way, but Arnie's shoe is stuck...

Shaking off the memory, Stromwell enters a deli controlled by Thorne for the meeting.

Elsewhere, Batman approaches an elderly priest and asks for his help.

Thorne acts affable, but Stromwell seizes him and demands to know where his son is. Seeming genuinely surprised, Thorne swears he had nothing to do with Joey's disappearance. Calming down, Stromwell accepts Thorne's invitation to sit - then realizes he has been set up as Thorne and the deli owner run out the back. A bomb inside the deli explodes. Stromwell is knocked unconscious, and trapped by the flames, but Batman enters and pulls him free. When Stromwell regains consciousness, Batman confronts him, asking him to give up his criminal ways and turn state's evidence. Stromwell acts defiant, but Batman decides to take him on a "tour" - first to Arnie's old neighborhood, where he started as an ordinary drug peddler, then to Sunrise Foundation, a drug rehabilitation center. Inside, Stromwell is shocked to find his estranged wife, Connie, who is attending to Joey, suffering from severe drug withdrawal pains. Stromwell rages, but is brought up short when Connie said it was one of his own dealers who got Joey addicted.

Appearing contrite, Stromwell agrees to hand over files incriminating himself and Thorne to Batman. But at the empty office he leads Batman to, Stromwell slips Batman a stack of dummy files, and uses his distraction to grab a gun, saying he won't go down so easily, and once he's finished with Thorne, he'll "rescue" Joey from the rehab center. Then they are both attacked by Thorne and his gang, who overheard a bum that witnessed Stromwell's escape at Batman's hands. Batman subdues Thorne's thugs, while Stromwell flees, with Thorne himself in pursuit. As Stromwell runs, he finds himself back at the old rail yard, and remembers the rest of the flashback: Just before the train hits, Arnie manages to get his shoe free, and stumbles out of the way - straight onto the next track as a second train is bearing down on him. Michael pushes Arnie out of the way, and the train roars over him, Arnie screaming "Michael! Michael...!" Stromwell collapses, sobbing "Michael... Michael..." A voice answers, "I'm here, Arnie." The old priest steps into the light - Father Michael Stromwell. He wasn't killed, but lost a leg - something for which Arnie never forgave himself. Out of guilt, he angrily says he doesn't need Michael's help, to which Michael reminds him of the current dismal state of his life: his family is broken, his son is gravely ill, his empire is crumbling, and his enemies are closing in. Michael appeals to Arnie, asking him to do the right thing: "[F]or yourself, for your son, for me, your little brother." Arnie hugs his brother, sobbing.

Then both of them are menaced by Thorne, with a gun, but Batman arrives just in time to save them. The police arrive on the scene. Thorne is arrested, and Arnie, arm in arm with his brother, prepares to give a statement to the police. Batman, his work done, slips away into the night.

Cat Scratch Fever

Selina Kyle stands trial for multiple counts of grand theft. The judge informs her that the penalty for her crimes is up to twenty-five years in prison. The fact that she committed her thefts to benefit animal rights causes is not a mitigating circumstance, but the fact that she helped Batman to save Gotham City from "annihilation" (the release of the viral plague stolen by Red Claw), she is handed a relatively lenient sentence of five years probation - a decision that receives heavy applause from Catwoman's fans in the gallery. However, the judge calls for silence and warns Selena that if Catwoman breaks the law again, she won’t be so lucky.

Bruce watches the news of Selina's sentencing. Alfred wonders why Bruce isn't more pleased, knowing how attracted Bruce was to her. Bruce says he's not convinced that Selina's reformed and decides to keep tabs on her. Besides, he adds, the idea of starting a relationship is dubious, since she is in love with Batman, not him.

Selina returns home in joy that she is free, but Maven sorrowfully tells her that Isis is missing. Maven accidentally left a window open and Isis escaped.

Determined to find her cat, Selina heads out to the fish market and asks about Isis but no one has seen her. Selina continues her search and finds a couple stray cats but Isis is still nowhere to be seen. Just then, a couple of thugs arrive and snatch the cats in a net. Selina confronts them over their kidnapping but they refuse to explain their actions and attack when Selina tries to stop them. Selina holds up her own against the thugs but they manage to gain an advantage over her and Batman is forced to step in. The two almost share a moment but the police arrive and Batman leaves. Unfortunately, the thugs claim that they were only trying to find new homes for the strays and that Selina attacked them. Selina denies it but Renee Montoya arrests her anyway.

Meanwhile, Roland Daggett watches as Dr. Milo injects a viral strain into a rather large dog that instantly becomes feral. Dr. Milo explains that the toxin acts almost instantly and just a nip will spread the disease. Daggett is pleased and tells Dr. Milo to complete his operation "by tomorrow night." Following orders, Dr. Milo takes Isis, whom had been captured, and injects her with the toxin. Selina is released from jail and discovers that Bruce has posted her bail. She thanks him for bailing her out but she only thinks of him as a friend. Bruce understands and warns her that the arrest could be bad for her. Selina is unconcerned and is more interested in why her assailants had an attorney from Daggett Industries working for them. Bruce warns her to keep away from Daggett and she assures him, "You won’t see Selina Kyle anywhere near Daggett Labs." She did fail, however, to say that Catwoman wouldn't be.

Suspicious of Daggett's motives, Bruce talks to Lucius about Daggett and learns that he's coming out with a new drug but no one really knows what it's for.

Believing that Daggett is up to something, Catwoman breaks into Daggett Labs and finds Isis. Concerned, she releases Isis but the virus takes hold and Isis bites her. The commotion attracts Dr. Milo and the thugs. Selina manages to escape but Isis runs away and the toxin starts to take effect. Catwoman becomes dizzy and clumsily chases after Isis but loses her and falls. Fortunately, Batman arrives and takes her to a hideout. Batman tends to Catwoman and learns about the bite and that something was done to Isis and several other animals. Elsewhere, Daggett complains that the operation is moving too slowly. Dr. Milo assures him that it'll be only a short while as he sent Paunch for the antitoxin in case of an accident. However, Batman reaches Paunch first and interrogates him for information about Daggett's plans. Batman manages to figure out that Daggett is planning to infect stray dogs and cats with a virus, which will blanket the city in a matter of weeks, then make a fortune selling the antidote. Unfortunately, Daggett and his henchwoman arrive and she fires on him with a machine gun. Batman manages to elude the gunfire but Dr. Milo releases an infected dog, which chases after him.
While the dog chases Batman, Daggett sends his thugs after him to make sure the job is finished. For a time, Batman manages to elude the dog and runs for Selina's hideout but the dog and the thugs catch up with him on a frozen lake. Making matters worse, the ice is thin and Batman can't run. The dog manages to catch up with him but Batman sprays it with a dose of the antitoxin causing it to calm down. Though the dog has stopped attacking, the thugs shoot at him, causing the ice to break. Batman and the dog fall into the water but only the dog emerges. Batman is okay, however, and grabs onto the thug’s legs from under the ice. Frightened, they shoot the ice and fall in themselves. Batman then captures the thugs and cures Catwoman.

Returning home, Selina discovers that she's now considered a hero, but without Isis, the victory seems empty. While she mourns the loss of Isis, a basket, holding Isis drops down. Isis happily jumps into Selina’s arms and both pet and owner are re-united.

Batgirl Returns

A jade cat from the Han Dynasty is stolen. Batman is instantly on the scene but Penguin starts shooting him with electric blasts from his umbrella. Batman prepares a batarang but it's hit away by a joker card. Joker and Two-Face advance on Batman along with Penguin. Before they can get to him, however, Batgirl arrives and tells them to back off. She quickly manages to beat the villains down and goes to see Batman is okay. Grateful, Batman holds Batgirl in close for a kiss.

Just then Dick calls her and awakens Barbara from her dreams. He offers to take her to get a pizza but she refuses it. Just then, she receives a newspaper that has a headline showing that a "priceless statuette [was] stolen from Gotham University." Her interest piqued Barbara decides to take a break after all.

At the University, Catwoman investigates the break-in and is interrupted by Batgirl. The two briefly fight but Catwoman claims she's innocent and proves that the crime isn't her style. In spite of this, Catwoman refuses to go with Batgirl to the police. Batgirl insists and a fight is about to ensue but Robin arrives causing Catwoman to flee. Robin and Batgirl give chase but Catwoman manages to escape. Batgirl then explains that Catwoman is innocent and scolds Robin for rushing in. Robin angrily leaves telling Batgirl to stay out of the way.

The next day, Barbara finds a message for "The Winged Mouse" and learns of where Catwoman will be later that night.

Batgirl arrives at the Bayshore pier and finds Catwoman waiting for her. Catwoman offers a truce and proposes a partnership. Batgirl agrees on the condition that Catwoman gives herself up if she's lying.

Meanwhile, Robin calls Bruce and learns that he won't be back from a business trip in time to help with Catwoman.

Batgirl and Catwoman go to the Stacked Deck to find information. They interrogate "the chemist" to find out who melted the padlock into the university but he runs before revealing where it was made. A fight ensues in the bar forcing the two to flee. They steal a motorcycle and are chased by the police. The duo manages to escape and judging by the Chemist's reaction Catwoman deduces who's behind the Jade Cat robbery.

Catwoman takes Batgirl to Roland Daggett's laboratory, the same one used to make the virus that infected Isis. Looking around they find the cat but it's a trap. Dagget and his goons capture Catwoman and Batgirl and take them to vats of hot chemicals. Daggett explains that he stole the cat because it was what Catwoman would have stolen and he needs the money to start over as he was left broke after his last encounter with Batman. Daggett continues by saying he'll have Batgirl and Catwoman shot and then thrown into the acid vats to destroy the evidence. Fortunately, Robin arrives and deals with the thugs before they can execute Daggett's plan. The trio beats Daggett's thugs and Catwoman goes after Daggett.

Catwoman manages to catch up with Daggett and takes the Jade Cat. Daggett attacks Catwoman with a metal rod but only manages to make her angry. Catwoman pushes Dagget over and his leg is caught on a chain hanging over an acid vat. Looking for revenge over the virus incident Catwoman prepares to drop Daggett into the acid but Batgirl catches the chain and saves him. However, Catwoman makes a break for it and Batgirl is not strong enough to pull Daggett up. Robin arrives and takes over for Batgirl allowing her to go after Catwoman. Using a bola she manages to catch Catwoman who confesses she always intended to steal the Jade Cat. Catwoman then offers to team up but Batgirl refuses. The police arrive and take Catwoman into custody who claims Batgirl is innocent. Unfortunately, Catwoman escapes the police and takes their car. Robin wants to go after Catwoman but Batgirl assures him there will be another time.

The Mechanic

While pursuing the Penguin's thugs Eagleton, Falcone and Sheldrake in their getaway vehicle, Batman and Robin stop short when a dividing bridge opens between them. The bridge comes down, crushing the Batmobile's front half.

The Batmobile limps to a secret garage operated by Earl Cooper, the Batmobile's designer and mechanic. He says he will need a few days to repair it, and in the meantime gives them two Batcycles to ride.

In the Penguin's hideout, Falcone brings an acquaintance to him, Arnold Rundle who works for an auto parts company. Rundle says that he has traced a pattern of exotic car parts being ordered and sent to one location: Earl's garage. Penguin is delighted.

Penguin and his thugs invade Earl's garage and take Earl and his daughter, Marva, hostage. At first, Earl refuses to help Penguin, who is intrigued to know why he is so loyal to Batman. Earl explains that Batman saved his life, twice. Earl was an engineer for a car company, who quit in protest when the company leaders refused to listen to his warnings about serious safety defects in one of their cars. His former bosses sent thugs after Earl, but Batman saved him. Several months later, Earl had been unable to find another job, when Batman appeared again in his run-down Batmobile and asked for Earl to design and build him a new one. After it was completed, Batman kept Earl on to maintain and upgrade it.

Penguin turns his attention to Marva, forcing Earl to cooperate.

Batman and Robin are called in to pick up the repaired Batmobile. With Falcone watching from the shadows, Earl tries to slip a warning to Batman, saying repeatedly that Marva is down "in the basement," and emphasizing that he has fixed the car's air conditioning.

As soon as they drive away, Penguin follows in his own car, taking Marva along as a hostage and leaving Falcone to guard Earl.

Earl has been forced to rig the Batmobile with a remote control held by Penguin. Penguin has a fine old time sending the car on a crazy ride, with the Dynamic Duo trapped inside and unable to control it. Batman presses the eject button, but it has been disabled. Finally, Penguin decides to end the game. He drives the Batmobile to the roof of a parking structure and prepares to send them off the edge. Batman realizes that "down in the basement" is a slang term in race car driving for crashing. Remembering what else Earl said, Batman presses the air conditioning switch, and the ejector seats fire, launching Robin and he to safety. The Batmobile goes off the edge and explodes, and Penguin believes he has won.
Back at the garage, Falcone receives the news of the Dynamic Duo's death with jubilation. Unable to contain himself, Earl knocks Falcone out and ties him up, then cries, believing that his friend is gone and his daughter is doomed.

Batman and Robin parachute down, and attack Penguin and his thugs. Penguin tries to get away, dragging Marva along, but Batman stops him and rescues her.

Batman apologizes to Earl for letting Penguin trace him, and assures him that from now on, future parts will be ordered through dummy corporations so no one else can. Earl, feeling no regrets, launches on an enthusiastic description of the newer, better Batmobile he's going to build.

At Stonegate Penitentiary, Penguin has been put to work in the license plate factory, scrubbing the finished plates. He comes across one that reads "1BAT4U", and tears it in half in a rage.
