Testament to the human capacity for change, this is an eye-opening and gripping investigation into the psyche of child sex offenders which introduces a psychological treatment programme that has the potential to stop cycles of abuse.

With unprecedented access to prisoners, whose identities are protected for their own sakes as well as for their victims, the documentary offers first-hand experience of sex offenders’ distorted thought patterns as well as their capacity for change – showing how expert psychological treatment, combined with blunt feedback from fellow offenders, helps bring them out of denial for their actions and into the process of rehabilitation.

The Worst Offenders: Can They Change? also features actor Colin Moy who takes on the role of a child sex offender in order to give viewers insight into the way their minds work, and to illustrate how the remarkable rehabilitation programme can change thought patterns and put an end to abuse.
