Lucy's high school has officially gone weird. An anonymous Instagrammer is taking photos of Hills High's best and worst dressed students. Luckily, Lucy has a plan. She's ignoring it until it goes away.

Lucy's popularity plummets as she's blamed for the strict new student dress code. And to make matters worse, there's something majorly wrong with it.

Lucy tries to convince the Principal that the school dress code is unfair to girls. Dave has a brilliant idea and the gang attempt to enlist the cool kids to help with a cunning plan.

Lucy's plan backfires, making her a social outcast. And to make matters worse, she's angered the resident school bully. Then things are going from bad to worse ... to totally sucks.

Lucy has become the laughing stock of the school, and decides to make it worse by entering the uniform competition with a distinctly unconventional design.
