Dreamers. Victims. Murderers.

Years after the horrific murders that made the name Charles Manson synonymous with pure evil, the three women who killed for him remain under the spell of the infamous cult leader. Confined to an isolated cellblock, the trio seem destined to live out their lives under the delusions that Manson created - until empathetic grad student Karlene Faith is enlisted to rehabilitate them. Convinced they are not the inhuman monsters the world believes them to be, Karlene begins the arduous process of breaking down the psychological barriers erected by Manson. But are the women ready to relive and to confront the horror of what they did? With an all-star cast including Hannah Murray (Game Of Thrones), Merritt Wever (Nurse Jackie), Suki Waterhouse (The White Princess) and Matt Smith (Doctor Who, The Crown), boundary pushing auteur Mary Harron directs this provocative new look at one of the most shocking crimes of the 20th century.
