On February 4th, 1997, Louise Woodward, an 18-year-old au pair from Cheshire, dials 911 in Boston. She tells them she’s trying to revive 8-month-old Matthew Eappen, who is unresponsive. Within days authorities arrest her and charge her with his murder.

Louise's legal team sets out to prove that she didn't shake Matthew to death and that his injuries occurred earlier. Two jurors explain why they came to the verdict they did and whether they believed the defense's claim that it was a witch hunt.

The shock and horror of the trial continues after the verdict. Those caught up in it reveal how the case still impacts them today. Dr. Patrick Barnes explains why he’s changed his mind about the science. Was the victim forgotten in all the hysteria?
