Academy Award–winning director Errol Morris (The Thin Blue Line, The Fog of War) turns his eye toward cult leader Charles Manson in the upcoming true crime Netflix documentary CHAOS: The Manson Murders.

Based on the nonfiction book by journalist Tom O’Neill with Dan Piepenbring, CHAOS reexamines the Manson family’s 1969 killing spree with input from O’Neill himself. O’Neill began researching the case in 1999 for an assignment, uncovering over the ensuing decades a sprawling conspiracy that includes CIA mind control experiments like MK-Ultra, LSD, and even Manson prosecutor Vincent Bugliosi. With these findings in mind, CHAOS looks to answer whether the official story of the Manson murders is actually the whole truth.

“It was managed and manipulated,” O’Neill says of the Manson story. “I know that what we were told isn’t what happened.”

Later in the trailer, O’Neill claims, “Manson became exactly what the CIA was trying to create.”
