Paige and Frankie take on public high school but quickly discover life at Sierra High is not what they thought it would be; Dirk, a recent Sierra grad and legend, tries to help Bernie and Amelia acclimate to their new school.
Paige, Frankie, Bernie, and Amelia begin their first day at Sierra High School. Paige and Frankie are disappointed when they learn that they will not have any classes together, but they decide to make the best of the situation and try to work through it. While Paige enjoys the new school and immediately makes several new friends, Frankie believes that she does not fit in after having a bad first day, as she has difficulty making new friends and keeps getting her hair caught in her locker. Paige cheers Frankie up and convinces her that it will take time before she fits in and makes new friends. Frankie becomes happy when several students recognize her and Paige from Bizaardvark. Meanwhile, Amelia realizes that her teacher and none of her classmates like her except for Bernie, who cheers her up. Dirk returns to the high school to perform a dare in which he uses rocket-powered leaf blowers to propel him through a wall. In the post-credits, Paige cuts Frankie's hair as they do their latest video about their first day of school.
