I'll Be Gone in the Dark is based on the book of the same name and explores writer Michelle McNamara's investigation into the dark world of a violent predator she dubbed the Golden State Killer. Terrorizing California in the 1970s and '80s, the Golden State Killer is responsible for 50 home-invasion rapes and 12 murders. This series gives voice to the survivors and their families, documenting an era when sex crimes were often dismissed or hidden in shame. A timely inquiry into our macabre preoccupation with true crime and a cautionary tale of the dangerous lure of addiction, the series is a riveting meditation on obsession and loss, chronicling the unrelenting path of a mysterious killer and the fierce determination of one woman to bring the case to light.
