Former “Smallville” star Allison Mack is speaking publicly for the first time about her role in the NXIVM sex cult.

Mack, long known as Keith Raniere‘s chief enabler inside the group, lays out her path into the organization on “Allison After NXIVM,” a new seven-episode series within CBC’s “Uncover” franchise. In the premiere, released Monday, she tells host Natalie Robehmed how she fell under Raniere’s spell and joined the network of women who catered to him, Variety reported.

Mack recounts having daily coerced sex with Raniere and says she shifted from victim to perpetrator as she rose in the ranks, becoming his trusted lieutenant and pressuring other women to seek the same supposed “help” she was receiving — encounters that ultimately amounted to rape, according to the outlet.

Raniere secretly controlled NXIVM’s women’s group, DOS, where Mack held “slaves” and dictated everything from their food intake to their daily movements. Among the women she drew into the organization was India Oxenberg, daughter of actress Catherine Oxenberg, one of the first public critics of the cult, the outlet reported.

The podcast opens up with Mack revisiting her June 2021 sentencing, recalling how her family listened as the court detailed her actions.

“Oh, my God, my poor brother behind me, having to hear this about his sister,” she said through tears, according to Variety. “My poor mom! I’m so sorry, you guys. I can take it, but like fuck, you guys, I’m so sorry. I don’t see myself as innocent, and they were.”

Mack says she didn’t fully grasp the severity of her actions until she faced prosecution. In the podcast, she describes the slow process of recognizing what Raniere had done to her — and what she, under his influence, had done to others.

Raniere was arrested in Mexico in 2018 and convicted the following year. He is serving a 120-year sentence for sex trafficking, racketeering, wire fraud and related crimes, the outlet reported.

Mack served nearly two years in federal prison and was released in July 2023.

“Allison After NXIVM” also features the first interview with Lauren Salzman, daughter of NXIVM cofounder Nancy Salzman. Lauren Salzman pleaded guilty and testified against Raniere, who had also been her lover, and was sentenced in 2021 to time served and five years of probation.
