Those who prey upon children for sex have committed crimes so abhorrent that most of us would like to lock them away for life. But in some cases, an offender can be rehabilitated - and, in the process, provide insight into the predator's mind.

This program goes inside a pedophile's distorted thought patterns while showing how expert psychological treatment, combined with blunt feedback from fellow offenders, can help bring such criminals out of denial and curb their deviant behavior. Following a professional actor who, using real criminal profiles, takes on the psyche of a child sex offender, the film examines Rolleston Prison's groundbreaking Kia Marama rehabilitation unit in Christchurch , New Zealand.
