Sarah confides to Mark about DOS, a secret women's group involving "masters" and "slaves." She struggles in her relationships with NXIVM, her husband Nippy, and her best friend. Nippy confronts the organization he's helped grow for 15 years. Sarah and Mark lament how many members they've recruited and question what to do next.

Mark, Bonnie, Sarah and Nippy strategize with Catherine Oxenberg about how to get her daughter, India, out of DOS, even though she wants to stay. "Jane," a former member and India's close friend, describes the appeal of the organization and of DOS, and why she left it all behind.

Catherine believes her daughter is in danger and wants her to come home. But she and the former members are unable to get the attention of the authorities, so they approach the New York Times. While weighing the pros and cons of going on record, Mark reflects on his time at NXIVM.
