To those on the outside, Kate Stark leads an idyllic life; a successful husband, an adoring daughter, and a beautiful home. But beneath the surface, her life is less than ideal; a husband preoccupied with his career, a critical and domineering mother, and a dark secret that not even her closest friends know: Kate is bulimic. As the pressures in her life begin to mount, Kate obsessively diets and exercises, and habitually binges and purges while adroitly hiding her eating disorder from all those around her. When Kate's bulimia eventually leads to a frightening accident that makes it clear to everyone that her illness is dangerous not only to herself, but to those closest to her, she is committed to rehabilitation in order to face the inner turmoil at the root of her disorder.
