Bianca is a content high school senior whose world is shattered when she learns the student body refers to her as "Designated Ugly Fat Friend" to her prettier, more popular friends. With her universe turned upside down, she ignores words of wisdom from her favorite teacher and enlists Wesley, a slick but charming jock, to help set her apart from the pack and erase her label forever. In doing so, she hopes to land her crush Toby, and to overthrow the school's ruthless label maker Madison.
