故事描述上世纪六十年代震惊美国的「曼森家族」邪教组织杀人案。丧心病狂的恶魔查尔斯-曼森（Charles Manson）诱导他的追随者在1969年连杀七人。加州没有死刑，因此曼森和三名参与此案的女性追随者在经历长达9个半月的审判后被判无期徒刑。如今年近80岁的曼森仍然被关在监狱里，他12次提出假释申请，但都遭到当局的拒绝。本剧的剧情设定在与真实历史事件相同的六十年代，David Duchovny扮演一名负责调查曼森案的洛杉矶警长。查尔斯-曼森原本只是一个不起眼的小罪犯，后来竟演变成震惊全国的邪教组织领袖，无数女性不仅对他投怀送抱，还帮助他犯下累累罪行。这名警长和他年轻的搭档将以卧底身份进入曼森的势力范围，最终摸清他和同伙杀害女演员Sharon Tate等四人和LaBianca夫妇两人的案件真相。和所有同类剧集一样，这名警长的个人生活和家庭生活充满了复杂性。
