The Vow, Honesty & Disclosure

Mark Vicente and Sarah Edmondson, high-ranking former NXIVM leaders, describe the dream and mission of NXIVM to build a better world.

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.

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.

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.

Catherine believes her daughter is in danger and wants her to come home.

Sarah, Mark, and Nippy contact additional news outlets to provoke outrage and pressure law enforcement to pay attention.

Catherine travels to Buffalo to meet with Frank Parlato, creator of "The Frank Report," to build a dossier of evidence.

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.
