The Hated documents the story of three very different murders where "The Hated" is either the victim or the killer. Ken McElroy bullied a small Missouri town for decades until people suddenly had enough. Robert Chambers grew up a child of privilege, hanging with the elite until one tragic evening in Central Park, and finally, a woman who changed America and quickly became the most hated woman in America. Madlyn Murray O'Hair has a target on her back.
