When an opposing player unknowingly steps on her knee during a game, injuring it and thus ruining her chances of getting the scholarship, she realizes that she will have to fund her education in other ways.

It is revealed that as a consequence of binge eating, her mother got sick and had to use the money set aside in her daughter's college fund to pay for treatment, a decision for which Aly has always resented her.

Aly also showers scorn on her family for their high-fat diet and lack of exercise, to the point of refusing to eat a cake that her mother purchased just for her.

Convinced that her overweight younger brother and mother use their struggles with weight as an excuse for everything wrong in their lives, Aly decides to go undercover, using a fat suit and facial prosthetics to make herself obese and unattractive, while deploying a hidden camera to record herself at school to prove personality can outshine physical appearance.

The film ends with Aly deciding to attend a house party while disguised, just to see how the same "friends" who loved her when she was attractive will still feel the same way now that she's fat.
