Documentary looking at how seven-stone teenager Emma's eating disorder is linked to her clinically-obese father Grant's condition. Discovering that his own weight was at the root of his daughter's illness was devastating for Grant, but fortunately, living in Lancaster means Emma can be referred to EDN (Eating Disorders Network), the area's only eating disorders charity. Over the course of six months, the programme follows Emma as she attempts to get to her goal weight of eight and a half stone.
