On August 9th and 10th of 1969, a series of brutal murders took place in Los Angeles. Seven people were killed, including actress Sharon Tate, who was married to director Roman Polanski.

Members of the Manson family, a kind of cult, were found guilty for the crimes. Manson and four of his followers were convicted of first degree murder and sentenced to death.

The prosecutor at the time said that Manson wanted to start a race war and trigger the end of the world. For decades, that was how the story went.

But a new film by legendary documentary filmmaker Errol Morris asks the audience to reconsider that. It's inspired by a book called "CHAOS: Charles Manson, the CIA, and the Secret History of the Sixties" by journalist Tom O'Neill, which makes the case that Manson might have been connected to the CIA's mind control program, MK-Ultra.

Errol Morris talks to host Jayme Poisson about "Chaos: The Manson Murders", unpacking the many theories about Charles Manson, and the culture of paranoia from that era of American history. The film is out on Netflix now.
