You think you know the NXIVM story. The secretive self-help empire. The sex cult headlines. The downfall of its leader, Keith Raniere. But the most famous woman at the centre of the story has remained largely silent. 

Allison after NXIVM from Uncover tells the story of Allison Mack: former Smallville actress, high-ranking NXIVM member, and convicted felon. With exclusive access following her release from prison, this series traces her astonishing path from Smallville fame to NXIVM’s inner circle — and her effort to rebuild a life in the wreckage. Through raw interviews and revealing conversations with those who knew her before, during, and after NXIVM, this season dives deep into the gray zones of influence, accountability, and redemption.

The finale. The aftermath of Ringel's trial, what happened, and what was learned. David and Mary Ann embark on a search for Chrissy’s body.

Watch David Ridgen's original television documentary from 2012, 'Confession to Murder Part I' and 'Confession to Murder Part II'.

David’s TV documentary about Christine comes out in the spring of 2012, publicly revealing details of the case for the first time along with key interviews including a face-to-face with Anthony Ringel. In the aftermath, police launch an undercover operation on Ringel. David and Mary Ann's work proves key and Ringel is re-arrested. Will Ringel finally go to trial and Mary Ann learn the truth?

The case against Anthony Ringel falls apart and he is freed. And Mary Ann says she's been kept in the dark. How did it happen, and is Anthony Ringel even guilty of what he says?

A decade after her disappearance, a previously uninvestigated local man comes forward at a family gathering and confesses to killing Christine Harron. Chrissy's mother Mary Ann is told that the case is a "slam dunk". And the outcome of an upcoming trial could mean she will finally learn the truth. But this is just the beginning.

Chrissy Harron didn’t feel well on May 18, 1993, and stayed home from school, but eventually her mother insisted that she get to afternoon class. Chrissy left, slamming the door, and would never be seen again. How can someone simply vanish, and did the local police find anything of use in their investigation?
