Sixteen-year-old Winter Mae Jones knows exactly what she wants: a career in fashion design. There's only one thing standing in her way - 'fat girls' don't work in the fashion industry. So Winter decides to take matters into her own hands. She goes on a diet, which at first makes her feel fab and in control. It's only when things get out of hand that she comes to realise that, not only has she less control than she thought, but also that her weight has nothing to do with what's holding her back.
