Culled from more than 100 hours of new and archival interviews with former Manson cult members, this two-hour special goes inside Spahn’s Ranch, where the Manson cult lived, to offer an intimate and terrifying look into America’s most murderous group.

Heather's happy life is interrupted by the news her long ago ex-girlfriend, Catalonia has passed away. She is asked to travel to Bishop's Cove, the small upstate New York town Cat grew up in to deliver the ashes to Cat's mother, father, and sister. While there, Heather will be confronted by demons both personal and, in the form of The Nameless. Now, more than Heather's perfect life is in danger. Her soul is too.
