Set after the events of the iCarly series finale "iGoodbye", Sam Puckett (Jennette McCurdy, reprising her role from iCarly) arrives at a food truck in Los Angeles, and sees a girl getting dumped into a garbage truck. Sam runs off to save her. Later, the girl introduces herself as Cat Valentine (Ariana Grande, reprising her role from Victorious). To thank Sam, Cat lets her reside at her grandmother Nona's apartment with her. The next day, Cat learns Sam took Nona to a retirement community called Elderly Acres. While heading out to see her, Sam and Cat run into three kids, Chloe, Max, and Darby, whom Nona was supposed to babysit. They take the kids with them to Elderly Acres, and the kids drive off on an electric wheelchair. Cat and Nona's neighbor Dice (Cameron Ocasio) helps the girls track down the three kids at Inside-Out Burger. The restaurant's manager faints after chasing around the kids on the wheelchair. The girls perform their version of CPR on him and save him. They are rewarded with free cheeseburgers for the rest of their lives. Afterward, Sam gets ready to leave, but Cat, not wanting to stay alone, asks her to stay. Sam agrees and they become roommates.

While Cat babysits two British girls, Gwen and Ruby, Dice notices that they have a "Pear Phone 6", a phone that has not yet been released in America. Dice strikes a deal with them to buy five new Pear Phones for $500. When he gets the package, he realizes they tricked him and sold him rocks instead. Cat visits the girls to see what went wrong, and ends up trading her bike for bibble, a fictional popcorn snack that she covets. However, instead of bibble, she receives a tin of cotton swabs. In the end, they trick Gwen and Ruby in a bingo game at Elderly Acres and get their stuff back with the help of two police officers who perform a fake raid. Dice gets his money back, Cat gets her bike back, and Sam gets her community service form signed.

The girls babysit a pygmy goat given to them by Dice. Their landlord's son, Dilben, threatens them with eviction as goats are not allowed in their apartment. Sam and Cat try to convince Dilben that they have gotten rid of the goat, but Dilben sees it and threatens to notify his father. He also warns them that they need to live with an adult. Sam, Cat, Dice, and Dice's client Goomer hatch a scheme to convince the landlord that the two girls indeed live with an adult and do not have a goat. They ultimately find out, however, that Dilben's father is not the landlord, and that the man he has been passing off as his father is, in fact, an actor.

Sam and Cat babysit Butler, a champion speed-texter, and discover that Sam is also a fast texter. She and Butler enter a texting competition and the two make the finals. Before the finals begin, Butler's mother glues Sam's hand to Cat's foot to ensure Butler can win more easily. Sam ends up texting with one hand, and Butler drops his phone on purpose to get back at his mother. Butler is content with his consolation prize, a bike. Cat, on the other hand, is shocked at the tiny size of the speed boat that she and Sam won. Neither of them care to meet the Vice President of the United States, another prize for winning the competition.

After Sam and Cat babysit a boy who tells them "You are the best babysitter ever!", the two argue about which girl he meant, and decide to make their next appointment a competition to see which of the two is the better babysitter, with the winner getting the master bedroom. When they babysit Daisy, Jarvis, and Sophie, they each do things to get the kids to like them. Sam and Cat then ask them which of the two they like better, and it turns out to be a tie since Sophie did not want to choose. The babysitters realize they work best as a team and share the master bedroom.

Guest stars: Rachel Eggleston, Justin Ellings, Ellee Jo Trowbridge

Dice asks Sam and Cat to babysit Goomer for one night, while Dice goes to Phoenix for hair modeling. They agree to do so, with conditions. The babysitting does not go as planned, as Cat accidentally puts Goomer's tongue-drop medicine in his eyes, blinding him the night before his big match against the undefeated John "Skull Crusher" Zakappa. During the fight, Goomer's chances are as good as his impaired vision, but he ends up winning after the "Skull Crusher" enrages him by making fun of Dice's hair (which is happening as Goomer's vision returns). Afterward, Zakappa cries that he wants a re-match and when he pushes Sam aside, after she tells him to accept the defeat, she wrestles him to the mat where the fight took place.

Guest star: Zoran Korach as Goomer

Sam and Cat find out they have been receiving negative reviews on a web site following a cancelled appointment. Sam calls up her tech-savvy friend Freddie who traces the authors of the reviews. It is discovered all of the reviews came from the same location, the house of a competing babysitting service. Sam and Cat then go to the house and confront those babysitters. Sam warns them to delete the reviews and threatens to beat them up, but Cat reminds her about the babysitter code. They then send Dice, dressed as a child with a hat cam, to spy on the competing babysitters and discover that they have set up a toddler-climbing competition in their basement to gamble. Sam and Cat go to their house again and threaten to upload the video of their competition unless they delete the reviews and stop babysitting.

Goomer's mother comes to town, having no idea her son is an MMA fighter. Sam and Cat must help convince her that he is a high school history teacher instead, because if she finds out his real job, she will take him back home to Louisiana. The girls set up a fake class at Hollywood Arts (the school Cat attends, going back to Victorious), but their plan falls apart when Mr. Sikowitz does not find an online charity Goomer is associated with. Goomer then admits to his mother that he is indeed a fighter; she becomes outraged and makes him pack his things. When the group enters an alleyway near Goomer's apartment, three thugs try to steal his mother's purse, prompting Goomer to beat them up. She then realizes the benefits of his talent and allows him to stay in L.A.

Gwen and Ruby return for another vacation from England and drive a wedge between Sam and Cat. They finally repay Cat with a real can of bibble, Sam with a vibrating motorcycle helmet, and both sitters with a special British toilet plunger. In reality, Gwen and Ruby are using these gifts for a revenge plot in retaliation for what happened to them in the bingo game (see "#TheBritBrats" above). Gwen reclaims Cat's can of bibble and sprinkles some bibble crumbs onto Sam's bed. Later, she paints Sam's motorcycle pink, while Ruby paints Cat's hand likewise. Sam and Cat argue with one another over these incidents, thinking they did it to each other for revenge. They part ways the next day to calm down. Goomer rationally points out to Sam that it could have simply been Gwen and Ruby's revenge. Nona relays the same logic to Cat. The girls gladly reunite and plot revenge against Gwen and Ruby. In order to trick the young Brits, they pretend to engage in a colossal fight in their apartment, and Sam uses the toilet plunger to make it look as if Cat has died. Never having wanted their revenge plot to escalate to death, Gwen and Ruby feel wretched about what they have done and quickly turn against one another, throwing a fit outside. Sam and Cat happily observe the fight, leaving the two to duke it out until they decide they need to call Gwen and Ruby's uncle.

Cat has a test coming up, so Dice, Goomer and Sam leave her to study, and head to a mixed-martial arts fight. When the three return, they find Cat asleep and handcuffed to a small, angry, foreign man. Sam's motorcycle is also missing, prompting her to wake up Cat, who cannot remember anything that happened because of a drug misuse. She also wonders why her hair is blue, but finds out she was with Nona at Elderly Acres earlier in the day. The gang heads there first in search of answers, and finds out Cat then went to a restaurant called Bots with an elderly man, who took her on Sam's motorcycle. So they head to Bots next and look through security footage. They discover John Zakappa (whom Goomer fought in "#GoomerSitting") stole the motorcycle, and Cat handcuffed herself to Zakappa's friend Hector. The gang meets with Zakappa to retrieve the motorcycle in exchange for his friend, but he gets tricked as Sam and Cat decide to keep Hector.

Sam discovers a safe in her bedroom closet, and attempts to crack it. The girls decide to look after Dice after he complains about having to go with his mother and aunt to Puzzle-Con for the weekend. Dice then complains after Sam and Cat do not allow him to go to a poker game with college students. But when Sam finally unlocks the safe, and the girls check out an abandoned room inside, Dice locks them in and sneaks out. The girls stay stranded in the room for a long time, until Goomer frees them. Sam and Cat soon realize that Dice never went to any poker game, but was instead dancing at a kid's birthday party, to earn money to replace his mother's laptop. They lock Dice in the safe as revenge for what he put them through.

When Cat saves an old man at Elderly Acres from getting hit by a scooter, the man's daughter asks the babysitting duo to look after her accident-prone son, Oscar. The boy is limited to using a rubber cup for his drinks, and eating cold, wet noodles without any utensils. Cat feels sorry for Oscar, so she plans to make his day as fun as possible, while trying to keep him safe with the help of the gang. However, a series of "predicaments" happen to Oscar while in Sam and Cat's care, leading his mother to chastise the duo when she picks him up. Oscar stands up for the girls, saying that even though he got hurt, he actually had fun.

On Halloween night, Sam dresses up like Cat while Cat dresses up like a genie. Sam and Cat are hired by Mr. Drange, a man Cat met by a graveyard, to babysit a creepy doll he calls Clarice. Dice gives Cat a spell book, and Cat tries to use a spell on him. She later suspects she may have turned him into a monkey, but Sam tries to convince Cat that Dice was not affected by the spell. Meanwhile, the doll seems to be in a new location every time Sam and Cat look at it, terrifying them. Mr. Drange returns and instructs them to take Clarice to a Del DeVille concert. While performing his latest song, Del recognizes Clarice, who has caused him nothing but trouble; consequently, Sam and Cat, as well as the doll, are escorted out by security guards. Afterward, Cat gets annoyed with Mr. Drange and complains, telling him to stop pretending the doll is his daughter as he is freaking everyone out. In a twist ending, the doll comes to life as a little girl, revealing that Clarice is really Mr. Drange's daughter.

Cat's audition to appear in a Peezy B music video ends in tears. She says the famous rapper was mean to her, ridiculing her hair, her dancing, and the hat she wore to the audition. This angers Sam, and she is set to take revenge on Peezy. As she confronts him, however, Peezy realizes she has the "swaggy spunk" and hires her to be his new assistant. This proves to be a hardship for Cat, as she faces difficulties babysitting without Sam, so Cat finds someone to take Sam's place. In the end, seeing how much it has affected Cat, Sam quits as Peezy's assistant.

However, they soon realize Sylvia and Janice are not on speaking terms after quarreling over a trophy for their show, more than 30 years ago.

They soon find out Ellie is overprotective of Poober and refuses to give it up.

The duo discuss ways to dispose of Poober and decide on sending it into outer space. They use Goomer's toy rocket for Poober's farewell, but before they launch the rocket, Ellie wants to have a final moment with her companion.

Sam eats all of the meatballs that Cat has prepared for a special moon dinner, and wants more. While the two are on their way to the store to get ingredients for more meatballs, Cat becomes obsessed with a pink shoe she finds in some bushes and then wears. Cat promises Sam she will make more meatballs after she finds the matching pink shoe. They eventually discover, through a clip from a reality show and a newspaper article, the shoe Cat found belongs to Stacey Dillsen (Abby Wilde, reprising her role from Zoey 101). They visit the hospitalized Stacey, seriously injured in the bike accident the two saw in the reality show clip, and they obtain the other shoe. They steal their way out of the hospital, and enjoy a fresh batch of meatballs to celebrate the special moon event.

At a convenience store called Handy Quick, Cat shows Sam an ATM which gives away "free" money whenever a special code is entered. Cat takes advantage of the ATM's quirk, getting money from it regularly, not realizing it is wrong. Even Sam warns her of the consequences, but the girls use the money to buy stuff anyway. Yokvish, the store's clerk, eventually catches Cat in the act of emptying the ATM, and informs an approaching policeman who arrests Cat on the spot. With Sam joining her roommate in the police car, the two unexpectedly find themselves in a high-speed pursuit of a stolen car on their way to the station. Due to a lapse in judgment that causes the arresting officer to fall asleep at the wheel, Sam ends up taking the law into her own hands and catches the car thief by herself. Later, the police repossess everything Sam and Cat bought with the stolen money, and inform the girls they need to pay back what they took from the ATM. Sam and Cat get off the hook when Yokvish does not press charges against them, and even more so after the police discuss the person Sam caught, a criminal wanted in three states, resulting in a reward that more than covers the money they stole.

As the time arrives for him to go home, Lucas informs his sitters that his brother Jepson is picking him up rather than his mother. Jepson's reputation makes him hated by most, and he mocks Cat for using the word nonconscious (instead of "unconscious"). It provokes Lucas into calling his brother lumpatious, which Jepson says is not a real word. Sam and Cat make a bet with Jepson that it is a word, but then find no proof of the word's existence in any dictionary, including the most authoritative Oxnard English Dictionary. Determined to bring the word into existence, the girls go to Oxnard and meet the "Word Keepers", who say the two must provide evidence of the word's use, and would accept a famous person's saying the word. The girls have no luck with their mission, until they catch the governor of New Jersey at Inside-Out Burger, where they get him to say lumpatious on video, despite the security surrounding his van. With the evidence they need, Sam and Cat show the video to the Word Keepers, who then add the word to the dictionary. Jepson then goes through the humiliation of losing the bet.

A gruff government agent named Mark Bonner confiscates the remaining soda at Handy Quick, and happens to see a sign advertising Sam and Cat as babysitters. Defying the ban, the girls involve themselves, along with Goomer and Dice, in a secret manufacturing operation. Cat figures out the soda's recipe and sales take off, yet the gang becomes paranoid and decides to shut production down. Before they can, agent Bonner shows up at the apartment, and the girls panic, assuming he knows about their illegal venture; he is only there so they can babysit his son. The gang briefly resumes production, this time to stockpile soda for themselves. When Bonner returns, he hears an explosion and quickly figures out what is happening. Just as he is about to apprehend the gang, Sam, Cat, Goomer, and Dice point out the hypocrisy of banning various products or habits that are only dangerous in excess.

When Kim reveals she wants a Fresno Girl doll more than anything, the duo agree to buy her one if she excels on her math test. And she does, so Sam and Cat stick to the deal and take Kim to the Fresno Girl doll store, but they get charged a steep price not only for the doll Kim wants, but also countless "accessories" for it. When Sam later accidentally damages Kim's doll, she and Cat take it back to the store, only to face another steep price for the repair. Sam gets revenge by feeding Fudge Piles (an extremely chewy dessert Cat came up with) to the salespeople, and announcing that merchandise is free while they are unable to talk. Meanwhile, a t-shirt Goomer wears for luck at MMA fights is missing, and he posts fliers to help him find it. The flier is misleading because of how Goomer designs it, making people think he is missing. So after a scout trooper named Randy and his troupe find Goomer, and not the shirt, they are expecting the stated reward and hold him captive until they receive it. Later, Cat discovers Kim lied about her math test and did not pass after all. In order to keep her doll, and also in exchange for Goomer's return, Kim agrees to a date with Randy.

As attempts to free Cat from the box prove futile, and the gang is just hours away from heading to Mystic Mountain, they bring the box to a local magic shop where a famous magician named Vance Anderson works. Vance has the tools to unlock the box, but he also behaves obnoxiously by flirting with Sam and insulting Dice. Regardless, Cat is still trapped after Vance confirms the box is defective.

Three months later, Del DeVille's new song is famous for Cat's eight second snippet.
