Allison Mack, formerly known for her role as Chloe Sullivan on the television series Smallville, became a central figure in the NXIVM scandal—a case involving a self-proclaimed self-help organization that was later exposed as a coercive cult.
Mack joined NXIVM in 2006, an organization led by Keith Raniere. Within NXIVM, she rose to a high-ranking position and was instrumental in establishing a secret subgroup called DOS. This subgroup operated under a master-slave hierarchy, where women were recruited under the guise of female empowerment but were subjected to branding, forced labor, and exploitation.
