Best known for door to door preaching, the Jehovah's Witnesses stand accused of a global sex offender cover-up. Avery Haines investigates the religious sect as it faces international pressure, and a $66 million class-action lawsuit, to change how it handles sex abuse allegations. From across Canada, to the United States, England and Australia she reveals how the religious sect's doctrine protects accused sex offenders and pedophiles and makes it virtually impossible for complaints to be reported to police.
