The official description for the series tells us, “Devotion: Obedience or Betrayal explores one of the world’s most controversial religious communities. For 50 years, Gloriavale has lived in isolation, bound by strict rules, until allegations of abuse and cover-ups shattered its secrecy. Now, with rare access, exclusive interviews, and decades of unseen archival footage, the docuseries reveals the secret life inside the community. Members vehemently deny they’re in a cult and defend their way of life, while former residents recount mistreatment, control, and deep personal cost.  As legal battles loom for this community, Devotion exposes a hidden world under intense scrutiny.”
