Lainey returns to William Penn Academy as the new music teacher. Lainey has a hard time adjusting to being an authority figure, but she realizes she might not be so bad at it when she discovers a kindred spirit in Principal Glascott’s niece, Felicia. Meanwhile, Coach Mellor struggles with Michael Jordan’s influence on modern-day basketball.

Hoping to gain respect among her colleagues at school, Lainey comes up with a misguided plan to give an awkward and insecure student a full makeover. Meanwhile, Principal Glascott and Coach Mellor take friendly competition to a new level when they are both romantically interested in the math teacher.

Lainey and Glascott encounter an overbearing parent and enlist the help of Beverly Goldberg. Mellor realizes he might want to start a family and be a father after CB shows him how to care for confiscated Tamagotchis.

Coach Mellor is cracking down on cheating, which leads him to take on the failing mathletes for the upcoming Math Olympiad. Meanwhile, Lainey helps CB deal with a challenging student.

After Mellor tells Lainey that sports are king at William Penn, she sets out to put on the Broadway hit musical “Rent” to show Mellor the arts are just as important as athletics. Meanwhile, Glascott and CB struggle to modernize the school’s outdated boy’s health education program.
