Hailey Banks is a resourceful teenager who dislikes taking risks, but this changes when a crazed professor from the future tells her that she must complete all the items in her to-do list to save the world. She is aided by her best friend and secret crush, Scott Denoga, and a talking phone named Beta. Hailey's newest list item is to ride all the rides at the county fair, including the Zero Gravitron, the scariest ride at the fair. During the ride, a group of Chaos Bots, who are trying to stop Hailey from completing her list, cause the Zero Gravitron to malfunction, but Hailey is able to stop the ride and save the day. Afterward, Kristine Sanchez, the most popular girl at Hailey's school, starts dating Scott, much to her chagrin, as one of the items on her list is to kiss Scott.

"Beta'd and Hooked": On the day of the Fish Taco Festival, Hailey, Scott, and Beta set out to catch a blue Ono fish called One-Eyed Jack, who had presumably attacked Hailey's father, Kai, once, to win the contest and complete another item on Hailey's list. While fishing on Hailey's Uncle Chunk's boat, Beta falls off the boat but is rescued by Jack, who turns out to be a very nice fish (Kai had misunderstood, and the fish was rescuing him). Hailey and Scott use fish sticks for their taco instead, which wins first prize, although by default, as the judge didn't eat any of the other tacos.

"The Wild, Wild Mess": At a reenactment of a western town, Hailey participates in a competition to become Sheriff for a Day and (thanks to being several years older than the other entrants) wins very easily, completing another item on her list. However, a dirt bike gang comes to wreak havoc around the town thanks to several videos Scott posted while riding his bike. Hailey decides to take on the leader, Road Rash, in a "bike-off", with the help of Betsy, a horse who was rejected by her previous owner in favor of a dirt bike, and they win. Hailey then passes off her sheriff badge to a young girl who admires her heroism.

"The Last Sand": Hailey and her father enter a sandcastle-building competition, giving her an opportunity to complete an item on her list by winning it. However, Hailey's self-proclaimed rival, A.C. Aychvak, has also entered the contest. He uses an army of small robots to help him build his castle, while Hailey recruits crabs to help build her own. Eventually, A.C. reveals a giant fan to blow away her castle, but Beta brings a squadron of pelicans to dump water on A.C.'s. However, this results in everyone's castles being ruined. Fortunately, Hailey's father has the only castle left standing thanks to his "triple-packing" technique, which, despite being very time-consuming, makes the castle very sturdy, resulting in Hailey and her father winning by default.

"The Show Must Go Wrong": Kristine is putting on a school musical she wrote called "Hats", which is an opportunity for Hailey to complete another item on her list by participating in a musical. She is initially nervous, but with help, she manages to overcome her fears and gets a non-speaking role as a hat rack. Scott is also involved in the musical as Kristine's duet partner. However, during the performance, Kristine is blinded by a spotlight and falls off a platform, injuring herself and being unable to continue. Scott attempts to perform the duet himself but fails miserably. Watching from the sidelines, Hailey works up the courage to join him, and they end up performing the duet flawlessly, making the show successful.

"Cubix Dudes": During a show by the performance artists "Cubix Dudes", Hailey and Scott discuss the former's next list item: taking a photo of herself with a strawberry moon owl. However, one of the Cubix Dudes injures his wrist, and the group recruits Scott, who turns out to have a talent for solving Rubik's cubes, to take his place. As a result, he is too busy to help Hailey with preparations for the owl, and after an argument, he goes off alone to join the Cubix Dudes on stage. However, a conversation with her father makes Hailey realize that it's important to support Scott, and she watches his performance. In addition, a photo taken of Hailey and Scott afterward includes the owl, thus completing the list item after all.

"Cos-played": After Hailey completes her 50th list item, the Professor (in a holographic recording) tells her about a mysterious orb in her closet. Hailey uses the orb to complete her cosplay for a convention that Chan Yee, the creator of her favorite comic book series, will be attending (getting her autograph is another of Hailey's list items). However, while waiting in line, a group of bullies trick her, Scott, and Beta into giving up their spots. Hailey's attempts to fight back result in the lead bully breaking her orb. She soon discovers the orb was for contacting the Professor, who heard the commotion and shows up with cosplay-dressed allies who scare the bullies away, allowing Hailey and the gang to get back in line and get the autograph.

"Road Trippin'": Hailey's latest list item is to go on a shopping spree by using all the gift cards she has ever been given. She and Scott manage to spend all her cards except for a $10 gift card to a burger joint called Butter Burger, which closed down due to health code violations. Fortunately, Beta finds one last Butter Burger restaurant open in Arizona, and Hailey and Scott take a bus there with Kristine joining them (as Scott had invited her to come since it's their "45-day anniversary" of dating). Throughout the trip, Kristine feels uncomfortable and left out and ultimately breaks down when she loses her favorite hat in the restaurant's ball pit. Kristine confesses to Hailey that she feels jealous of the latter's close friendship with Scott, while Hailey admits that she was afraid of losing Scott's friendship. The two girls eventually become friends.

"Escape Doom": Hailey, Scott, and Kristine go to an escape room to complete another item on Hailey's list. They are unexpectedly joined by A.C., who wants to prove how smarter he is than Hailey by leading the group. In the first room, A.C. solves all the puzzles with ease, but in the second room, he is completely useless, and he is forced to admit that he cheated by memorizing a tutorial for the first room. Shortly after, a group of Chaos Bots arrive and rig the escape room, causing the walls to close in on the gang and crush them. Hailey is forced to overcome her fear of leading and assigns everyone (including A.C.) a task to help them escape. They manage to succeed, although A.C. ends up taking credit for saving everyone.

"The Flamingo Must Flamin-Go": Hailey decides to go to the local animal shelter to adopt a pet since that is another item on her list to complete, even though her mother, Patricia, does not allow her to adopt pets due to a childhood incident. At the animal shelter, Hailey finds that the only available animal is a smelly, old flamingo named Frank, who goes crazy when he notices shrimp. After Hailey fails to train Frank to convince Patricia to let him stay, the flamingo escapes and is exposed to Hailey's family. As Patricia and Hailey are about to take Frank back, the former gets a call from her clients, who are selling their house. After Frank makes a mess of the sellers' house because they have a shrimp tray, the sellers begin to insult Patricia, who in turn tells them off and allows Hailey to keep Frank.

"Splatter of the Bands": Hailey wants to enter the "Splatter of the Bands", a contest where people throw tomatoes at a singer if they make mistakes; performing will complete another item on her list if she doesn't get pelted with tomatoes.

While they are rehearsing, Hailey meets a European band, and they invite her to perform a song with them since she has a great singing voice, and Hailey accepts the offer. However, the duo complains about even the slightest mistakes, and Hailey regrets her decision. On the contest day, Hailey's father starts singing with his friends, and Hailey ultimately decides to rejoin them. Ultimately, no one throws tomatoes at them, completing Hailey's list item. However, when her father and his bandmates admit disappointment over not being pelted, Hailey starts singing another song with them and gets splattered. Afterward, the European band starts singing but gets pelted almost immediately.

"Bringing Home the Beacon": Patricia owns a disused lighthouse inherited from her and Hailey's ancestor that has a history of the ancestor building it and mistakenly mounting the light pointing the wrong way, flooding the town with light and making him a laughing stock to the shame of his family. Hailey decides to try to fix the lighthouse to complete a list item that involves her fixing something for her mother. However, Patricia is already trying to sell the lighthouse to a businessman who plans to tear it down. Hailey and her friends do a project of renovating the lighthouse and seem to succeed, but it ultimately goes wrong and produces light resembling a disco ball; however, this makes the site attractive as an event venue, and Patricia decides not to sell it.

"Dance Like No Mom is Watching": With Beta taking time off to install an upgrade, Hailey decides to choose and complete a list item on her own, picking one to achieve the high score in a dance video game. After lots of effort, she finally manages to complete the final level and get a score above the previous high, finding out that her mother has a secret history of dancing in music videos years earlier, and her moves help Hailey learn how to beat the game. However, when Beta returns from his upgrade, he informs Hailey that she had already achieved the high score on the game (the previous high she beat was her own) but didn't remember it due to a brain freeze from eating a cold dessert.

"Kristine-ceañera": Kristine is celebrating her quinceañera, but she is annoyed at her father's interference, changing the ceremony in ways that suit the way he wants it rather than what she wants. In particular, he wants her to dance with Javier, somebody he finds a more suitable match for her than Scott. Javier and Scott end up in a hot sauce eating contest for the right to dance with Kristine, something that Kristine herself dislikes as she's turned off by this sort of macho display. While both guys get to the hottest sauce in the array, Javier ultimately wins, but Kristine then takes control by eating the legendarily hot Black Scorpion chili pepper whole, and then dances with Scott. Kristine's father apologizes for being so controlling.

"The Puffle Kerfuffle": One of Hailey's list items is to attend a taping of the Puffles show, featuring singer/dancer/TV host duo Kylie and Thacher, who proclaimed themselves best friends in their act.

When Hailey goes to the TV station to ask why, she finds out that the station owner would like to continue to air the popular show, but the hosts called it quits after their friendship broke up over a kiss. This hits Hailey personally, as she fears the same might happen to her and Scott's friendship should she complete the item of kissing Scott off her list. She then schemes to get them back together for a reunion show, with them ultimately performing together one more time, after which she finds out that the two were never actually best friends; Thacher's childhood friend was Bailey, whom he ultimately married. Bailey turns out to be uncannily similar to Hailey in terms of interests, making Hailey more confident about her relationship with Scott.

"Flippin' Out": To distract from the failure to capture a Chaos Bot, Beta suggests that Hailey get a varsity letter to complete another item on her list and improve her physical skills. She chooses cheerleading because she thinks it will be easy, but after meeting with Kristine and the rest of the squad, she discovers that it is much more difficult than she could imagine. After clumsy cheerleader Lucy is taken out of commission, Hailey is forced to replace her. She soon takes cheerleading seriously when Bored Murray, a notoriously uninterested student, arrives to watch their final game.

The next day, Hailey discovers two wild pumas in her front yard. Convinced that Becker misinterpreted her request, she and Scott try to return them to the wildlife sanctuary, only to get a call from Becker, who reveals that she got the shoes as promised. The pumas get loose and chase Hailey and Scott, but they are rescued by Becker, who is offended that Hailey thought the worst about her. Hailey apologizes and admits she would like to hang out with her again. As Hailey and Scott leave, Becker is convinced that Hailey is into her.

After they leave, Hailey and Scott decide to take Dwayne and Johnson to the concert with them. While there, Hailey also sees Patricia at the concert and tries to avoid her.

The Professor gives Hailey a new AI named Omega, but Hailey wants Beta back, and Omega agrees to help her. Hailey and Scott break into N.O.P.E. headquarters, where they find the Chaos Bot's remains. Its battery reveals an insignia that Hailey had previously made up, making her question if she created the Chaos Bots. Hailey and Scott manage to rescue Beta and escape. Later, the Professor reveals that the insignia is for an energy element that Hailey discovers in the future, which powers everything, including the Chaos Bots. After the Professor leaves, Scott reveals that not only has Kristine gotten onto Hat House, but she has also broken up with him, making the "Kiss Scott Denoga" item on Hailey's list more likely to be completed.

"Seas the Day": Scott is depressed over Kristine breaking up with him, so Hailey decides to cheer him up by taking him to Catalina Island, with Beta suggesting that they eat at a restaurant so that she can be open with her feelings. Hailey initially fails to cheer Scott up, but after a near-death experience, he returns to his usual happy self and they go to eat at the restaurant. While there, Hailey gets a call from Kristine, who reveals that despite breaking up with Scott, she does not want anyone to date him, resulting in Hailey ruining the moment she was going to use to open up to Scott and getting kicked out of the restaurant. Scott thanks Hailey for the day, although now she is feeling sad.

(who wasn't invited), Becker (who quickly leaves), Thad, Jonathan, Lucy, and Murray.

The game results in everyone doing or admitting to something embarrassing. Hailey finally gets the kiss card for Scott, but realizes that the kiss would be disingenuous and forfeits, admitting that she hates the game. Genesis admits that she too didn't like it and everyone decides to party how Hailey intended with even Becker returning.

"Sight for Dinosaur Eyes": Feeling that most of the list revolves around Hailey, Scott suggests that she do something for him for once as he has his own list full of ridiculous items. Before Hailey can respond, the Professor accidentally leaves behind blueprints for a mysterious device and Hailey becomes distracted by building it. To make up for it, Hailey takes Scott and Beta to Jurassic Journey, a low-budget theme park, which in actuality she is using as an excuse to find the material she needs to complete the device. The device turns out to be a growth ray and she accidentally enlarges an iguana. Beta increases his own size to combat it and Hailey realizes that since she made the device in the future, she also most likely made reverse features and shrinks the iguana and Beta back to their normal sizes. Hailey apologizes for shirking Scott, but he is happy that they completed an item on his list: see a real kaiju fight.

"Along for the Slide": Hailey and Scott ask Beta for something fun and he suggests climbing Mt. Oceanside. Becker just so happens to be going there to try the abandoned alpine slides, but she has secretly gotten over her crush on Hailey and finds it awkward. On the hike, the three are joined by Kennedy, a girl that Becker considers her rival due to her by-the-book behavior. Kennedy ends up being great help to the group, much to Becker's chagrin, but when she tries to sneak away to the slides, Kennedy follows her and they end up on a runaway slide. Kennedy admits that she likes her and Becker finally reciprocates. Afterwards, Becker tells Hailey that they should just remain friends, confusing her as she had no idea that she had a crush on her.

"Leather Jacket Hailey": Hailey feels that she is being pushed around and taken advantage of and is further incensed when Kristine returns to Oceanside for her show Hat House and has Hailey assist her. Hailey comes across a leather jacket that suddenly makes her more confident and tough. This results in her blowing off her duties, but making everyone else around her take control of their own situations. The rest of the kids assisting Kristine get the wrong idea from Hailey and plant an explosive in one of her hats. Hailey uses the jacket to muffle the explosion before giving a speech to everyone about being open with your feelings. Scott gives modeling a try, though he immediately gets over it, and Hailey openly gets mad at her science project partner.

"In a Pinch": Hailey is tasked with looking after Clawdia, the school's crab mascot, by Ms. Jackson.

Seeing as how Clawdia needs to be at a tetherball tournament that evening, Scott uses his marionette skills to make Clawdia look alive.

Hailey uses Clawdia to get the last coin out of the couch just in time for Patricia to sell it, though Kai ends up buying it back.

The two become partners, but A.C. begins to claim the app for himself. The case is taken to a mock trial with Hailey representing Scott and A.C. representing himself. Hailey makes a strong argument while A.C. gives a very weak one. The trial rules in favor of Scott, but all he wanted was a jar of Dingles, much to Hailey's chagrin.

To Hailey, Scott, and Beta's surprise, they find out that the factory is run by beagles who are financially capable. Chip reveals that he tests the chips while the beagles handle all the money issues. Feeling bad, Hailey decides to let the beagles out and play, which Chip equates to them having vacation time. In the end, it is revealed that Auntie Bland herself wrote the false information about Dingles.

Eventually, Alphred and Beta battle each other within their coding and Alphred comes to the conclusion that he is, in fact, Beta's father, or rather his great-great-grandfather. Beta is relieved and Alphred is ultimately taken back to the lab, but not before Beta finally gets a sense of belonging.

The girls become nervous and try to hide their involvement. The authorities blame their friend Tina for the crime, but Hailey comes clean, only for Kennedy to conclude that it was A.C. himself who detached the jet ski causing it to get destroyed. A.C. admits the wrongdoing and is forced to do five hours of beach clean up as punishment.

"Lady and the Trampoline": After mocking Beta, Hailey is tasked with completing the Big Bounce at Trampoline Town. Hailey is afraid to do so because a trio of older kids mocked her when she tried to initially. She manages to face her fear and Scott agrees to distract the teens while she completes the Big Bounce.

Hailey manages to make it to the end of the Big Bounce, where she sweats up a storm, but ultimately manages to complete it.
