After decades of silence, Hefner's former number one girlfriend Sondra Theodore shares her story detailing how she was groomed by him to participate in his increasingly abusive sex life. Sondra's testimony shines a spotlight on Hefner's mechanisms for controlling and breaking women.

Never before heard stories from Playmate Susie Krabacher, mansion employees Stefan and Stella Tetanbaum, and Sondra Theodore reveal the dark truth that Hefner was the Mansion's Predator Number One.
