After learning that the New York Attorney General's chief investigator is interested in building a criminal case against Keith, Catherine travels to Buffalo to meet with Frank Parlato, creator of the anti-NXIVM blog "The Frank Report," to build a dossier of evidence. Meanwhile, we're introduced to Toni Natalie, one of Keith's former girlfriends, who takes us back to the '90s to share her experiences and the challenges she faced with Keith during the days of his first company, Consumers' Buyline.

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. Mark and Bonnie return to Clifton Park for the first time since leaving NXIVM and confront their memories of Keith and the curriculum. Sarah, Bonnie, Mark, Nippy, and Catherine face a shocking development in the case.
