The Justice Brigade was investigating a jewelry store that got mysteriously robbed at night. Sungirl used her powers to look for clues while Iceboy followed her, and Heatgirl used her Heat Sensing Vision to look around in the dark while Aquaboy followed her. Sungirl pointed at one of the jewelry cases with her powers and saw a perfect circle cut. Sungirl said, "Hey, Iceboy, look." Iceboy said, "Whoever did this must have had sharp claws." Heatgirl said, "And is female. Look at these footprints." Sungirl cast her powers ahead of them and saw two footprints that looked like they came from a woman's boot. They also found a piece of hair on one of them, and Sungirl picked it up with tweezers. Sungirl said, "I wonder." Sungirl scanned the hair with her watch and opened it, and the analysis told her it was cat fur. Sungirl said, "Cat fur?" Iceboy said, "Maybe a cat just passed by and left one of their hairs behind." Sungirl thought about it and said, "Maybe, but I'm not sure." After they left the jewelry store, a specific lady hiding in the shadows on the rooftops glanced at The Justice Brigade and watched them go. Then, the lady jumped off the rooftop and landed on her feet as a cat would. When it was all clear, the lady left with the jewels from the jewelry store and got away with them.
The next day, The Justice Brigade thought the case through on a rooftop. While they were there, they spotted something flying toward them. Heatgirl used her Heat Sensing Vision to get a closer look and saw it was a bat coming their way. Heatgirl shouted, "Hit the deck!" The Justice Brigade hit the deck, and the bat flew super-fast over them. Sungirl said, "What's a bat doing in the middle of the day?" Iceboy said, "How can it fly that fast without flapping its wings?" Sungirl said, "Let's follow it." The Justice Brigade followed the bat and saw Batman catch it. After Batman put his Bat-a-rang in his utility belt, The Justice Brigade flew up to him. Heatgirl pointed at Batman and said, "So, you're our culprit." Sungirl put her hand in front of Heatgirl and said, "Relax, Heatgirl, he's a good guy like us." Heatgirl said, "How do you know?" Sungirl flew next to Batman, stating, "This is Batman, Gotham City's hero. And he's in Beverly Hills; why?" Batman said, "I've been on the trail of Catwoman. I had her traced to this city." Iceboy said, "Catwoman. Guess that explains the claw marks we found at the jewelry store and the woman's shoeprints." Sungirl said, "It also explains how the thief cut a perfect circle in one of the cases. But we still don't have an answer to the cat fur we found." Batman said, "I do. Catwoman has trained some cats to help her with her thieving. And since she did, they might have helped her in the robbery last night." Heatgirl said, "Well, at least now we know who we're after." Sungirl said, "Maybe we can help. If she's after jewels, she might strike at the museum tonight."
The Justice Brigade and Batman staked out the museum from the rooftops and saw a Siamese cat using one of her claws to cut a hole in the museum's window. Then Catwoman petted her head and snuck into the museum through the hole her cat cut in the window. Sungirl said, "This is going to be too easy." Sungirl shot one of her Sun Beams at the museum, broke the window, and set the alarm. When Catwoman heard the alarm, she saw all the exits on lockdown. Catwoman hurried out. Catwoman said, "What happened?" The Justice Brigade showed up, and Catwoman saw them. Sungirl said, "You got caught in the act; that's what." Catwoman pointed at The Justice Brigade and said, "I know you; you're The Justice Brigade." Then, a Batrope tied around Catwoman. Catwoman looked up and saw Batman on a rooftop. Batman said, "Who's helping me catch you."
Catwoman then used her claws to cut herself free. Catwoman said, "You'll have to do better than this to catch me." Sungirl shook her fist and said, "How about this." Sungirl punched Catwoman's face, and Iceboy hit her in the stomach. Heatgirl flew down to Catwoman, but Catwoman used her whip to catch her and throw her at Sungirl. Catwoman then snapped her fingers, and her cats showed up. One shredded Iceboy's costume with her claws, and Iceboy froze it in his ice. Catwoman then threw a caltrop on the ground, and Batman tripped over it. She then tied The Justice Brigade in one of her Bolas. Then Catwoman got away, but they took the cat that Iceboy froze in ice to jail once the police arrived.
The next day, Batman and The Justice Brigade got in Batman's Batmobile and drove around town looking for Catwoman. They found her at The Las Angeles Animal Shelter. Once Catwoman saw the Batmobile, Batman and The Justice Brigade got out and got ready to fight. Iceboy said, "You're outnumbered five to one, lady." Catwoman said, "Am I?" Catwoman activated the jewel she stole from the jewelry store and blasted the first floor of the animal shelter with it. Once she did, five cat monsters walked out and destroyed the first floor of the animal shelter. Catwoman then checked her beauty in her compact, closed it, and said, "Have fun." Catwoman then snapped her fingers and pointed at The Justice Brigade and Batman. Batman said, "Take 'em down." The Cat Creatures and the superheroes ran up to each other and took one.
Sungirl blasted her cat creature with one of her Sun Beams and blinded it long enough to kick it. Heatgirl's cat creature shredded her costume, but Heatgirl set the cat creature's butt on fire, and it panicked. Then it ran off and sat in the fountain. Iceboy froze the feet of his cat creature so he couldn't move a muscle while Batman tied his cat creature's legs together and made it fall to the ground. The last cat creature grabbed Aquaboy with its tail, but Aquaboy made it super windy and blew him around in circles until he let go. Then he took the water from the air and splashed the cat creature. Once the cat creature got wet, it panicked and ran off. Sungirl jumped ahead of Catwoman and said, "You're out of cat creatures." Catwoman said, "Plenty more where those came from." Catwoman pointed up, and Sungirl looked at all the cats in the animal shelter. Sungirl said, "There are enough cats in there for a whole army." Catwoman made the necklace around her neck glow and said, "That's the idea." Sungirl then glowed her eyes and shot Catwoman's necklace with her Laser Vision. Then it exploded, and all the cats they beat returned to normal. Catwoman said, "You ruined my plan but still have to beat me." Catwoman heard Batman say, "No problem." Batman threw his Batrope at Catwoman, and it tied around her and caught her. Then Catwoman fell to the ground, and Sungirl put one of her feet on her. Sungirl said, "Now, who's laughing."
The police arrested Catwoman, took her to jail, and The Justice Brigade returned everything she stole. Sungirl showed them the jewel she destroyed and said, "Sorry about this one, though." The police chief said, "We'll see what we can do." The police drove away with Catwoman and her stolen loot while The Justice Brigade had one last talk with Batman. Sungirl said, "It was an honor working with you, Batman. Maybe our paths will cross again someday." Batman said, "Maybe. We'll see, but they need me in Gotham City for now." Batman then got in his Batmobile and drove back to Gotham City.
