A model son since he was adopted, Robbie Ward, now in his midteens, experiences wildlyy erratic changes of mood, a dangerous condition that his parents must face and find help for, before it is too late.

The Young family seems to be living the American dream. Willard "Pepper" Young is a successful sales executive who provides amply for his wife, Lily, and children, Gwen and Bud. Bud Young excels both academically and as the quarterback of his high school football team. Tragically, their lives are shattered when Pepper crashes the family station wagon, hurtling Bud into a coma. Equally devastating is the fact that it was Pepper's alcoholism that precipitated the accident. While Lily devotes herself fully to Bud's recovery, younger sister Gwen is bewildered at the course of her family's fate. Bud has overcome athletic and academic obstacles in the past, but he now must face the greatest challenge of his life - recovering from a severe brain injury. Bud's fate depends upon Marcy Ethridge, a tough but caring physical therapist whose strength and knowledge push Bud to the limits of his capabilities over long months of painful recovery. While Marcy achieves small daily victories with Bud, Pepper and Lily grapple with the terrifying prospect that their son will never be the same. This loss is compounded by the months, even years, it will take to gauge the extent of his recuperation. Through it all, Bud leans on Marcy as his therapist. Though at times he calls her his worst enemy, ultimately, she's his greatest friend.
