When Tom Seymour, a child psychologist, plunges into a river to save a young man from drowning, he unwittingly reopens a chapter from his past he’d hoped to forget. For Tom already knows Danny Miller - when Danny was ten Tom helped imprison him for the killing of an old woman. Now out of prison with a new identity, Danny has some questions - questions he thinks only Tom can answer. Reluctantly, Tom is drawn back into Danny’s world - a place where the border between good and evil, innocence and guilt is blurred and confused. But when Danny’s demands on Tom become extreme, Tom wonders whether he has crossed a line of his own - and in crossing it, can he ever go back?
