When a heat wave approaches the Thundermans house, the kids ask for a swimming pool but are forced to hold a yard sale in order to be able to pay for it. Max accidentally sells Barb's Electress box to a boy obsessed with Electress and he and Phoebe must get the whip back before it explodes. Nora struggles to sell her bows.
It's very hot in the Thundermans house because of a heatwave. Max and Phoebe are lying on the couch while using Nora and Billy to drag in a house and turn on the water so that they can make the room into a private water park. Hank and Barb bust the kids and confront them about having a water slide in the house. Phoebe argues that they wouldn't need a water slide if they had a swimming pool. Hank says they can have a pool but Barb shuts them down. She then agrees to let them have a pool if they contribute money to buy one.
The Thundermans decide to hold a yard sale after Max's suggestion. Billy and Nora are excited about the yard sale. Max and Phoebe bring out their old junk for their yard sale. Billy wants to sell his action figures. Hank is surprised to see Nora's Bows in a box. Nora says that she wants to sell them because it's been so hot lately, one of her bows melted in her hair and got stuck there. Max and Phoebe make fun of the box of their mom's old Electress stuff. They laugh at how they barely know anything about what she used to do as superhero Electress.
Phoebe starts looking at the content in the Electress box. Barb comes over and asks her to return the box upstairs because she can't sell it. Phoebe just reacts as if the items are so lame. Barb explains that the box contains her Electress Whip. Hank calls Barb aside and asks her why she forgot to mention that in the wrong hands, the whip could be very dangerous. But Barb explains that she wouldn't risk leaking that information to her supervillain - wannabe son. She reminds Phoebe to take the box upstairs but Phoebe gets distracted when her "Cute Boy" app notifies her of a cute boy outside. She runs out leaving the box unattended.
At the yard sale, Nora struggles to sell her bows. So she decides not to sell any at all. Whenever someone tries to buy a bow, Nora pulls it back and tells them that she doesn't want their dirty bow money. Hank tells her that he knows the bows mean a lot to her but she should be willing to let them go. Nora asks to sell Dr. Colosso instead. Hank advices Nora to look for the bows she no longer wears and sell them instead. Nora goes upstairs and turns all of her bows into a dress to prove that she wears all of them.
Max finds a little boy named Cedric who wants to buy comics. He runs inside and grabs Barb's Electress box and sells it to Cedric. Phoebe comes back into the house after the "cute" boy tried to get her to pull his finger. She finds the Electress box gone. Oops! Barb notices that the box is missing but Phoebe tells her Max probably took it. Phoebe runs to Max who admits that he sold the box. Phoebe asks Max to run after the boy to get the box back. She then indirectly lies to Barb that Max returned the box upstairs.
Max follows Cedric and refunds him for the Electress box. He rings the bell at Cedric's house. Cedric turns out to be a big fan of Electress and already knows that is the real Electress whip. So, he refuses to give Max the whip back. He tells Max that he will only give the whip to Electress herself. Max tries to take it by force but Cedric rings an alarm on him. Max runs back to Phoebe to explain what happened. So, the Thunder Twins plan to get the whip back without letting their mom and dad find out. Barb gets concerned that she can't see the box. So, she brings an old machine to help her track her whip in a jiffy. That's old people for really fast. Luckily, her old machine takes forever to perform updates.
If Cedric wants Electress, the Thunder Twins will give him Electress. Max asks Phoebe to pretend to be Electress.
Max knocks at Cedric's door to introduce "Electress" to Cedric. Phoebe is dressed up as Electress and uses electric gloves to make Electress-like sparks to convince Cedric that this is really Electress. Cedric invites them inside his room. Max and Phoebe are surprised to see all the Electress posters and newspaper extracts on Cedric's wall. Cedric starts asking them questions about Electress. They don't know that Blackbolt was a "she" and not a "he." They don't know Electress' favorite battle. They don't know anything about her sidekick. They just assumed that their mom was their dad's sidekick. Phoebe panics and does an Electress "spark attack" but it backfires and zaps Max. Cedric puts two and two together and concludes that this is not the real Electress. Cedric throws the whip at Max and Phoebe, binding them together.
Back at home, Billy is frustrated that Phoebe and Max bailed on the yard sale yet it was their idea in the first place. He starts making bad impressions of the twins. He tells Hank that he is mad because he sold his favorite toy, Sergeant Flargeant. They decide to go back into the house because there's nothing else to sell. Then they notice Nora selling her bows. Billy wonders why Nora is selling her bows and Nora says she's doing it because Billy gave up his favorite toy. So she can't be the only one who won't give up something. Hank is proud of Billy and Nora.
At Cedric's house, Phoebe and Max are still tied together with Electress' whip. It gets hot and starts sparking, meaning that it's about to explode. Cedric comes back in to taunt them. They beg him to release them before the whip explodes but Cedric wonders why he should believe them. Phoebe agrees to start over. She introduces herself as Monica and introduces Max as Ross. And for all he knows, they could be Electress' children. Cedric argues that there is no way Electress' kids would know nothing about her. Phoebe and Max admit that they are horrible kids because they know nothing about their mom. Their mom is an amazing superhero and some random kid knows more about her than they do.
Then all of a sudden, there are huge electric sparks. Barb makes an epic super-charged entrance into the room as Electress. She frees Phoebe and Max and thanks Cedric for being a heroic Electrolyte. Cedric asks if those posers are her kids and she denies them. There is no way her kids would be so reckless as to compromise their safety and identity just for a couple of bucks. She then takes Phoebe and Max and zaps away with them. Cedric is left with a hole in his carpet.
The following day, the Thundermans are seated in a tiny balloon pool. Hank tells the kids that they got what they earned. Phoebe complains about working so hard just for that. This makes Billy mad because Phoebe and Max did nothing. He tries to attack her but Hank stops him. Barb says they're proud of Billy and Nora. Nora wonders why they're proud of her when she only sold one bow... to Dr. Colosso.
Max comes in carrying an Electress comic book and they all start asking their mom more about her life as Electress. Phoebe and Max apologize for not knowing much about it yet their dad brags about his "Thunder Man" life all the time. She tells them that the kids are her biggest accomplishments.
