It is Harley's 13th birthday, but it seems no one remembers.

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.

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.

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.

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.

Harley makes one last effort to divert Rodney's attention so the entire family can leave the store unscathed. Rodney catches up to them though and bans them. When Suzy confronts him about his customer relations, pointing out she was watching the children's live streams as they were getting caught, Rodney retracts his ban. Harley and her siblings celebrate, only to realize they will not be getting any pizza because Suzy reminded them that she watched their live streams. This disappoints the children and Tom.
