It is Harley's 13th birthday, but it seems no one remembers. Harley believes her parents will feel guilty about forgetting her special day, and decides to use that "guilt" to get the best seat in the family car as a present—the sweet seat, reserved for the oldest child, which is Rachel. To ensure she gets the sweet seat, and as soon as her siblings become aware of what day it is, Harley urges them to stay quiet about it for the rest of the day and distract Suzy and Tom from remembering. In trying to keep her birthday a secret, Harley endures demands from Daphne to keep quiet, as well as getting into trouble. Later that night, Georgie reminds Harley how precious celebrating birthdays with the family is becoming, as the older siblings will soon be leaving home. That prompts Harley to let go of her desire for the sweet seat and let the family know about her big day. As for that sweet seat, she can wait.

When Suzy and Tom refuse to buy the children another tablet to replace the one they broke, Harley comes up with a plan to raise money for that tablet.

With Ethan's help, she books an Asian music student, Bai Hsu, to stay in the Diaz home for two nights. Bai's accommodations are not exactly as he expects since the children are trying to keep Suzy and Tom from becoming suspicious. When Bai cannot sleep in the Diaz home on the second night, Harley brings him to her father's store, where he ends up sleeping by a raft. The next morning, Harley, Ethan and Georgie discover Bai and the raft are gone. Tom tells them he sold the raft to Bai, whom he recognized in selfies Rachel posted online. As Tom did not accept any additional money from Bai, Harley's effort to fund the new tablet falls short.

With the help of her siblings, Harley comes up with a proposal to decide who gets the attic, and the children offer to clean out the attic as well. They settle on a battle of boys vs. girls, with the two genders agreeing to a series of backyard competitions. When figuring out what kind of competitions, going on what they cleaned out from the attic, they make use of Harley's past inventions.

Harley figures out a way to make the playhouse safe but finds out it has been discarded, so she, Rachel and Georgie are looking for a store that sells the kind Daphne had. They discover a toy store in Marshport with only one but worry the store owner will not sell it to them because of the family's history at that store. Although the girls successfully manage to purchase the new playhouse, they realize Daphne had memories with the old one in the form of various dents to it. Feeling sad, Harley discovers from Ethan that the old playhouse is in a nearby dumpster, so she, Rachel and Georgie recover the parts to it and put it back together for Daphne.

As the Diaz family prepares their home for Christmas, Harley needs to know how long to steam pasteles and winds up calling Abuela to find out. Harley is hoping Abuela will ask whether the family will spend Christmas with her in Florida, but when the question does not come up, Harley is prompted to bring the family there. They initially take a plane to Florida, but when a storm in the flight's path causes the plane to land in Columbus, Ohio, they settle on two small, uncomfortable rental cars to continue their journey. The discomfort is short-lived as Harley spots a huge tour bus belonging to a rock band that is not around to claim it. With Tom having a license to drive that kind of vehicle, the family continues their trip in the bus and decorates it for the holiday. Daphne suddenly realizes her doll "Deathnee" is missing, which Harley traces back to the rental cars, so the family tracks down the doll, while Suzy confiscates the children's electronic devices which had distracted them when the doll went missing. The family ends up at a camp where they meet another family with a little girl named Joyanne, who has Deathnee and is not about to give her up. Georgie makes a deal with Joyanne, getting back Deathnee in exchange for toys she collected for a toy drive. As the Diaz family gets ready to leave, Tom sees a penny he hopes will bring good luck, but as he picks it up, the contents of his pouch, which includes their money, credit cards and electronic devices, falls into the camp fire. Adding to the misery, the bus later breaks down, with the impact causing Harley's glass ornament for Abuela to break.

Hoping to reach Abuela's by Christmas, the Diaz family turns to a repairman named Buddy Burtz, whom Harley discovers is a middle child just like her, often ignored by his brothers. With the backlog at the Burtz repair shop, Tom offers to pay double to get the bus fixed, while Suzy attempts to withdraw the necessary funds from the bank, which falls through. Harley finds out that Buddy's brothers are taking part in an annual holiday race known as the Iron Elf but are not interested in having Buddy on their team due to his fear in one event the year he took part. Harley strikes a deal with Buddy, having him compete with her family in the race, and if they win, he will fix the bus for free. Buddy ends up facing the event he struggled with before, but with Harley believing he will overcome his fear, he succeeds, helping the Diaz family pull out the victory. Harley gives the trophy to Buddy, while the children donate the presents they won on Georgie's request.

As the two brainstorm, they settle on running a camp for youngsters in the Diaz backyard, which Harley hopes will also fund a special quinceañera gift. Suzy has no problem with the camp idea as this would keep Daphne, Lewie and Beast occupied. Daphne has no interest in the camp, so Harley has Georgie keep an eye on her.

Harley's dislike of Aidan continues to consume her as it is now affecting her at school. She asks her mother for tips on how to deal with him, knowing her long-term battle with Bethany is similar. Suzy tells Harley to simply agree with Aidan, as that is what she does to avoid arguments with Bethany.

Suzy and Bethany also hear the two bickering, since they are volunteering at the school's bake sale, and they start to argue once Harley brings up how she has been coping with Aidan using Suzy's "yes for no distress" technique. Meanwhile, Ethan is trying to get new subscribers for his web channel by filming a new segment starring Lewie and Beast at Tom's store, but when they see the segment is a failure and are no longer allowed to film in the store, they go to the bake sale and end up capturing Suzy and Bethany's arguing on camera.
