Mark Vicente and Sarah Edmondson, high-ranking former NXIVM leaders, describe the dream and mission of NXIVM to build a better world. Bonnie, Mark's wife, tells him she is worried about the organization.
Bonnie leaves Albany for Los Angeles to make sense of it all. She tries desperately to get through to Mark, who reassures her all is well. Meanwhile, Mark remains loyal to Keith, but a series of phone calls begin to sow doubt within him.
Sarah confides to Mark about DOS, a secret women's group. 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.
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.
Sarah, Mark, and Nippy contact additional news outlets to provoke outrage and pressure law enforcement to pay attention. Barbara Bouchey, a former board member, shares her insight into NXIVM, reflecting on her time in Keith's inner circle.
Catherine travels to Buffalo to meet with Frank Parlato, creator of "The Frank Report," to build a dossier of evidence. Toni Natalie, one of Keith's former girlfriends, share hers experiences and challenges she faced with Keith.
As the group gathers evidence for their FBI testimonies, they express their beliefs about how the curriculums of SOP and JNESS, men's and women's groups within NXIVM, may have laid the foundation for DOS.
Keith hasn't been seen in Clifton Park for weeks, and the team gets a tip on where he might be. Catherine meets with India, who maintains her position. Sarah, Bonnie, Mark, Nippy, and Catherine face a shocking development in the case.
