"A powerful and humane exploration of the "insanity defense," through one heartbreaking case. A three-year-old boy dies, having apparently fallen while trying to reach a bag of sugar on a high shelf. His grandmother stands accused of second-degree murder. Psychologist Susan Nordin Vinocour agrees to evaluate the defendant, to determine whether the impoverished and mentally ill woman is competent to stand trial. Vinocour soon finds herself pulled headlong into a series of difficult questions, beginning with: Was the defendant legally insane on the night in question?
