When a teenaged boy is discovered stabbed to death in the woods adjoining the local high school, a wave of shock ripples through the suburban community of Newton, outside of Boston. Assistant district attorney Andy Barber is used to dealing with murder and its after-effects, but with his own son, Jacob, also a student at the school, he too is anxious for a swift arrest and conviction. But as the kids appear to be stonewalling the cops and the investigation stalls, evidence emerges that ties Jacob to the crime - and suddenly Andy faces a very different challenge: preventing his son from being convicted of murder. Together with his wife, Laurie, the family closes ranks in the midst of an increasingly hostile community as Andy prepares for the trial of his life, the one trial he cannot afford to lose. Especially when the emergence of his own dark family secrets threatens to undermine Jacob's defence. And as the drama reaches its climax, Andy and Laurie have to face every parent's toughest questions: how well do you really know your own child, and how far would you go to save them?
