Life story of Madalyn Murray-O'Hair, sometimes called 'America's most hated woman' because she firmly fought for the rights of atheists and against the omnipresence of religion in the USA. People talk about her while a narrator tells us the background and motives of Murray-O'Hair. Short clips of her are shown as well. Halfway through, the filmmaker starts focusing solely on the mysteries surrounding the end of her life, involving a disappearance and 1,500 golden coins.
