— Nora to Billy
Phoebe and Max Thunderman are twins in a family of superheroes. When their parents go out for dinner, they leave Phoebe and in charge. After Phoebe invites her best friend Cherry over, she accidentally exposes her superpowers while trying to stop an argument between her younger siblings, Nora and Billy.
Phoebe and Max Thunderman are twins in a family of superheroes; Phoebe strives to use her powers for good, and Max embraces the dark side.
A fourteen-year-old girl, Phoebe Thunderman brings dinner to the table. Seated right to where Phoebe is standing is her twin brother, Max Thunderman, who hopes to become a supervillain one day. Next to Max is their little brother Billy Thunderman and their youngest sister Nora Thunderman wearing a pink bow. To Nora's right are their parents Barb and Hank Thunderman. These are the Thundermans – a family of superheroes who recently moved from Metroburg to Hiddenville to live a normal life as a suburban family.
Barb says it's good to eat dinner as a normal family. Phoebe opens up the raw turkey dish and tells Nora, "hit it sis!". Nora then uses her heat vision power to cook the turkey in just a matter of seconds. Phoebe uses her telekinesis power to get forks to the dinner table. Billy super-speeds to the fridge to get the lemonade. Max uses his telekinesis to grab dessert. Phoebe won't let Max have it because the dessert cake is for later. So, she stands up and uses her telekinesis to pull the cake towards her. The Thunder Twins use their superpowers for some time until Max releases the cake, hoping it would fall on Phoebe's face but Phoebe ducks, letting the cake hit the wall. Billy freaks out about the cake. Hank then grabs him with his superstrength and suspends him in the air. He asks the kids for once to eat dinner like a normal family without using their superpowers. He then puts Billy down. Afterwards, he realizes that he is missing his Peruvian sauce. Now he has to fly to Peru to get the sauce. He stands up, says "Thunderman Away..." and flies through the ceiling, leaving broken pieces of the ceiling on the floor. Max says that's always funny before revealing to Phoebe that he had been hiding the sauce this whole time.
The next day, Phoebe is on the phone with her new friend Cherry planning for a girls' night. Billy wonders why Phoebe is so excited about having a friend. She and Max already have more powers than Nora and him. What do they need friends for? Nora then makes fun of Billy for not having friends. Phoebe asks them to be nice and love each other. Well, except for Max cause he's evil. Max puts his arm around Phoebe and asks her, where is the love? Phoebe replies that their love died when he beheaded her dolls when she was five. Max excuses himself to go to his lair to do evil stuff. He opens a slide on the living room that leads to the basement. But Hank and Barb make stop him and start making fun of Max's Lair. Hank tells the kids that he is taking Barb out for dinner and Max and Phoebe will be in charge. Phoebe tells Billy and Nora to behave and not listen to their brother, then walks towards the door. Barb stops her by sending an electric shockwave to the door using her electrokinesis superpower. She tells Max and Phoebe that they're not going anywhere. They have to babysit their younger siblings. Phoebe tells them about her plans with Cherry and Max tells them about his plans of not babysitting. The parents refuse to listen. Phoebe asks them to get a neighbor to babysit but the parents are concerned that Billy and Nora would expose their powers. Nora and Billy don't help Phoebe's argument when they start playing "laser tag" where Nora uses her heat vision as lasers to zap Billy's feet. Barb reminds the kids that they can't risk exposing their powers because they left the crime-fighting job to lead a normal life.
Left alone with the kids, Max wonders how he is going to become a supervillain if he has to sit at home babysitting Nora and Billy. He then comes up with an idea to use them in his latest project. He tells Phoebe that she deserves to have her girls night while he babysits the kids. Max asks Phoebe to bring Cherry over but Phoebe reminds him of the number one rule set by their parents: no non-supes in the house. Phoebe refuses and plans to call Cherry to cancel their girls' night. But Max manipulates her by scaring her that if she doesn't hangout with Cherry, Cherry will find a new best friend and leave Phoebe alone. Phoebe falls for Max's plan. Max asks Billy and Nora to behave. Before texting Cherry to come over, Max telekinetically takes away the phone from her. He then writes the text message on behalf of Phoebe in an informal style. Phoebe is surprised that Max wrote exactly what she would have written.
Max asks Nora and Billy to follow him on the slide into the lair. Billy goes first and lands on Max's bed in the basement. Nora slides and falls on Billy. Max asks them not to touch anything and walks away. The kids decide to touch the things in the lair. Billy finds a button that says "Press here to destroy Pluto." He presses the button. Unknowingly to Billy, a planet explodes from the solar system. Nora then finds Dr. Colosso's cage in the lair. She opens it and they both scream at each other for a long time before the bunny asks Nora to close it. Max then comes back and asks the kids to help him carve his initials onto the moon. Billy uses his superspeed to power up the machine while Nora uses her heat vision to carve on the moon. Nora and Billy agree that Max is the best babysitter ever.
Meanwhile, Hank and Barb's dinner turns into a birthday party entertainment when one of the caterers reveals that the "Thunderman" they had hired did not show up. Hank steps in to play "Thunderman" since people will think that he's just a normal entertainer and not the actual Thunderman. It turns out he already had his Thundermans costumes under his clothes. Hank even uses his superstrength in public and claims that the people at the party will think he's just using props. When a kid asks him to fly he just falls over and they're satisfied that Thunderman can fly. Barb worries that Hank is too careless and could easily expose them. Luckily, no one thinks he's the real Thunderman.
Back at the house, the Thunder Monitor announces that a non-supe is approaching. Phoebe puts the Thunder Monitor back into its place, then presses a button on a penguin that swaps the Thundermans superhero portrait on the wall with another photo in which they're not wearing superhero costumes. She then runs to open the door for Cherry. Cherry comes in being all excited. She is glad to finally see the Thundermans' house. It's not like Phoebe was hiding it from her. Of course not, they're best friends and she wouldn't hide anything from her best friend. Yeah, right. Cherry and Phoebe then go on to take a good number of selfies. When Cherry places her purse on the penguin, the portrait switches back to the Thundermans superhero portrait. Phoebe presses it again. Thinking it is for fun, Cherry presses it again and asks why Phoebe did that. After swapping the photo back and forth, Phoebe pulls Cherry away to make brownies in the kitchen.
Down in Max's lair, Billy and Nora get bored after Max stops talking to them to concentrate on his experiments. When they ask him what to do, he shows them a box labelled "Not Evil Enough" for them to choose what gadgets they want. They find the Nose Hairalyzer which is used to grow nose hair on anything and uses it on Max's chair. Billy uses it on his chest to grow chest hair, disgusting Nora.
In the kitchen, Cherry asks Phoebe who she's crushing on. Phoebe is reluctant to say initially but Cherry reveals that she already knows Phoebe's crush is Cole Campbell. Cherry pressures Phoebe into asking Cole to hang out later. Billy and Nora arrive at the kitchen fighting over the Nose Hairalyzer. Billy tries to zap Nora with it but Nora quickly blocks it with a couch cushion. "That's it!", declares Phoebe, before lifting the kids in the air with her telekinesis. Cherry watches in shock. Phoebe realizes what she just did. Max quickly enters the room. Shocked.
Cherry realizes that Phoebe has superpowers. Max asks Phoebe why she never told him she had powers. Phoebe tells Cherry there's a perfectly good explanation. But then she panics and freezes Cherry. The Thunder Kids are surprised. Max smiles because Phoebe has done something bad for once. However, he realizes that it isn't funny anymore when Phoebe reminds him that he is the one who texted Cherry in the first place. So, they will both get in trouble.
The Thunder Twins promise Billy and Nora that they will work together to find a solution. But Max and Phoebe working together? Billy and Nora are not convinced of the idea and starts packing as they believe the twins are going to fail and they will be busted. Eventually, causing the Thundermans to leave Hiddenville.
Phoebe suggests coming up with some explanation to fool Cherry but Max suggests wiping Cherry's brain using his BrainMelt-3000. Phoebe doesn't like the idea of wiping her friend's brain. Max argues that Cherry is gullible and can't possibly have much memory to wipe if she is friends with Phoebe and is named after a fruit. Eventually, they adopts Phoebe's idea. She unfreezes Cherry and demonstrates to her that they were just rehearsing for a play. Billy and Nora are tied to ropes and Phoebe holds a remote which she is using to control the ropes making it look as if the kids are floating. Cherry accepts the explanation. But then, the brownies in the oven were finished baking. Billy forgets and superspeeds to the kitchen to grab the tray of brownies. Nora uses her laser eyes to cut the brownies into cubes. Cherry realizes that all of the Thundermans have superpowers. She takes her phone ready to post about it. Max freezes her this time. Max and Phoebe panic because none of them wants their powers exposed. Phoebe doesn't want to leave Hiddenville and lose her best friend while Max doesn't want to leave his evil lair behind.
The Thunder Monitor announces that the parents are approaching. Phoebe thanks Max for adding a parent warning alert on the monitor. The kids freak out. Max rushes the frozen Cherry into the closet to hide her from their parents. When Barb and Hank arrive, Billy and Nora try to distract them while Phoebe and Max carry Cherry all over the place, attempting to hide her. Unfortunately, the parents notice the twins acting abnormal. Barb recognizes it's Phoebe's friend, Cherry. The parents ask the kids to start packing since they can't risk being exposed.
Max stands up for Phoebe in front of their parents. He tells them that it was his fault for inviting Cherry to hangout with Phoebe so that he could have Billy and Nora in the basement. He tells them that they moved to Hiddenville to have normal lives and Phoebe deserves that and should not be punished for something that he did. Phoebe is touched by Max's speech. She suggests that the whole family pretend to be part of the musical and perform in front of Cherry to convince her that it was all a play. Cherry buys it! The Thundermans are relieved.
Phoebe and Max have a heart-to-heart talk where Phoebe thanks Max for standing up for her. Max tells her that he has a reputation to uphold, so they should keep the "nice" thing on the down low. Phoebe says she will never forget that Max did a nice thing to her. Max attempts to erase her brain with the BrainMelt-3000 but Phoebe threatens him.
Hank flies through the ceiling to get macademia nuts from Hawaii. Phoebe and Max look through the hole he left and both admit that they have a weird family. Then Phoebe notices that it says "NORA RULES" on the moon! Max angrily shouts, "NORA!"
